FOR RUGER® 10/22®


Although our popular TI25™ Advanced Composite Adjustable Magazines have not been available for some time, we are not able to offer "Rebuild Kits" that include all parts for the magazine less the stainless feedlip.  The feedlip is IDENTICAL to the old style Butler Creek steel lip magazines and this rebuild kit is perfect for repairing a old style cracked Butler Creek magazine or for upgrading the same to an adjustable magazine capability. 

The TI25™ Rebuild Kit includes the following parts:

1. Composite Left Side

2. Composite Right Side

3. Follower

4. Constant Force Spring & Bobbin

5. Screws with Mating Nuts for Assembly (3)

6. Screws for Position Adjustment (4)

In order to prevent any misunderstandings, the rebuild kit is NOT a complete assembled magazine and is sold for replacement parts or to assemble a complete magazine using your old style Butler Creek feedlip.  We have not tested with other manufacturer's feedlips and although its possible that other manufacturer's feedlip could fit, we are unable to guarantee the fit of any feedlips other than the old style Butler Creek steel feedlips.  

The TI25™ Advanced Composite Adjustable Steel Lip Magazine Rebuild Kits are a closeout item and although all parts are brand new and identical to the parts used in our TI25™ complete magazines, these Rebuild Kits are sold "As Is" with no returns and with no technical support for assembly, adjustment etc.  This Rebuild Kit will not be shipped to any state where high capacity magazines are prohibited nor can your credit card billing address be in a restricted state.     


Please note that product specs below will show the mag assembled with the feedlip. However, this Rebuild Kit DOES NOT INCLUDE THE STAINLESS FEEDLIP which can be obtained from an old style Butler Creek steel lip magazine.



Anyone that's shot .22 rimfire ammo knows how dirty it is, and a lot of the crud gets into the inside of the magazine which continues to make the mag less reliable. Now with our TI25 mag, that problem no longer exists. Three stainless steel cap screws make it easy to disassemble the mag into two separate halves for cleaning using the supplied allen wrench. Scrub the INSIDE with some hot soapy water, dry and reassemble and its as clean as it when it was new. Yep, it costs us more to make a mag that you can disassemble rather then just gluing it permanently together, but being able to disassemble it is the right way to make a mag!

Have you ever wondered (and cursed) about the amount of wiggle in all other 10/22 high capacity mags? A magazine should not wiggle that much in your gun, but it has to to fit... WELL NOT ANY MORE! It has been our experience that Ruger 10/22 rifles have some minor variations from one to the next which explains why one brand mag will run well in one gun and the same mag then not run in a different gun. What separates this mag from all others is the patent pending ability to micro adjust it for an exact fit in your gun for (1)FEED ANGLE, (2) FEED HEIGHT and (3) EJECTOR TO BOLT DISTANCE using the supplied 3/32" allen wrench. Four cap screws on the top of the mag that mate with your 10/22 receiver allow the mag to quickly be precision adjusted for an exact fit in your gun by minimally increasing or decreasing the individual heights of each of the cap screws (like leveling an appliance), resulting in a magazine that has minimal to no wiggle in your gun AND THAT WORKS!. The ability to quickly one time precision adjust it to your gun means that you can count on reliable feeding every time.

What is Advanced Composite material? Its a high pressure injection glass filled resin that has 2X times the impact resistance and 3X times the wear resistance of aluminum! Its weight to strength characteristics make it so strong that its used in the manufacture of airplanes. We tested one by driving a full size Dodge 2500 V10 onto the mag as shown in the picture. Although we don't recommend that you abuse your mag this way, we wanted to make sure there was no question about the strength of this mag! Of course its much less expensive to make a mag out of plastics of lesser strength, but the result is you wind up with a mag that will easily crack and break. Our TI25 magazines are designed to stand up to hard use. Don't settle for less!

We know mags! Our extensive testing in both full auto and semiauto guns combined with the power of state of the art CAD designing and CNC machining means that we've built this mag from the ground up for reliable functioning. We've seen other magazine manufacturers that have taken short cuts to save some money, and each time the reliability suffers. Our unique feed geometry was driven by reliability, not cost. Our customers repeatedly told us to make a mag that works... period... and that's what you can expect from a TI25 mag.

Our Model TI25 ADVANCED COMPOSITE STEEL LIP MAGAZINE could be the last 10/22 mag that you ever have to buy! If you want a mag that will give you many years of shooting satisfaction rather than disappointments and frustration; a mag that you will never want to throw away; A MAG THAT WORKS, then this mag is bargain priced and ready to become one of your favorite shooting accessories.

Review This Product


Thank you for your purchase. It is our goal to provide you with a mag that will provide you with many years of service and enjoyment. In order to get the maximum life and performance out of your mag, proper cleaning is recommended.

1.  Periodic disassembly and cleaning with soap, water and a toothbrush is suggested. Do not use solvents or other chemicals. Dry well and lightly spray spring and interior of mag with WD40 prior to assembly.

2.  We have tested and experimented with most major offerings of ammo and as expected, there is a HUGE difference in the feeding, performance and reliability of the different ammo brands. You will have a very difficult time adjusting the mag using some brands of “bulk” ammo since some of the bullet profiles are difficult to feed and many of the rounds are not full power which will result in poor or failed ejection.

We recommend that you test with CCI solid round nose MiniMags to minimize the effect of ammo on your adjustments, then after the mag is adjusted, bulk ammo should also work well within the limitations of the ammo.

3. Occasionally new mags will require a minimal break-in period as evidenced by the inability of the mag to keep up with the feeding speed required. If your ammo is sticking in the mag, you should:

A. make sure the mag is clean on the inside. Dirt and carbon and unburned powder will increase the drag on the bullets and will slow down the feeding speed and feeding ability.

B. Especially with new mags, the more the mag is used, the more the follower and mag will polish each other, much the same as a crankshaft and bearing in an automobile engine.  If you have a new mag and the follower is a little slow or weak to push the ammo uo, simply disassemble the mag into two sides by unscrewing the 3 side screws. Disconnect the follower from the spring, leaving the spring in the mag.  Manually slide the follower up and down on the inside of the magazine on the rails on EACH side to simulate use in order to accelerate polishing the follower and the mag rails to each other. Blow any dust out of the mag. Spray a light mist of WD40 on the INSIDE of both mag sides prior to assembly.  Re-assemble and you should be all set.  The more the mag is used the smoother it will get.

TI25 magazines for Ruger 10/22 rifles and similar firearms have the patented ability to be adjusted for a precision fit in your receiver. Each mag is adjusted prior to shipping and should be ready to use. However, since individual guns have varying tolerances, your mag is capable of being adjusted to satisfy three different requirements:
(1) Bullet Height
(2) Bullet Feed Angle
(3) Camber (left and right adjustment).

It may be necessary or desirable to adjust your TI25 mag for a more precise fit in your 10/22 for any of the following reasons:

1. to achieve a precision feed angle and ejector position;
2. to make the mag fit your gun based on variations in receivers;
3. to reset the magazine position after the screws have been previously “adjusted” and now the mag will not work;
4. to position the mag in relationship to other manufacturers’ receivers other than Ruger.

Adjustments should be made with the following conceptual understanding before beginning:

1. The magazine adjustment is similar in concept to leveling an appliance (such as a dishwasher). All four screws must always be in contact with the receiver. You never want to have a situation where only 2 or 3 are in contact and the remaining adjusting screws are not in contact.

2.Similarly, given that all 4 are in contact with the receiver, all adjustments are made in pairs. You would never adjust one screw. For instance, if you wanted the ejector to be farther to the right (toward the bolt), you would screw IN the two screws on the right hand side and screw OUT the 2 screws on the left hand side a corresponding amount. Picture a playground seesaw. When one side goes up, the other side has to go down.

3.Once the adjustment positioning is close per the SOP herein, adjustments are made in small increments, generally 1/2 to 1/3 of a turn. If you are turning and turning, you’re way off.

4.If you’ve already screwed the adjusting screws all the way in or taken them out, you’ll have to reset and then adjust them per the SOP herein.

5. If you adjust for hours turning screws in and out and in and out, it is possible to wear out the screw threads to the point that you will not be able to adjust them any more. The entire process of resetting the position and adjusting should take less than 15 minutes the first time by following this procedure step by step and only 2 to 3 minutes for subsequent mags once you understand the procedure.

6. If you are having difficulty, often it’s advantageous to have a shooting buddy help with the first one as you follow the procedure step by step.

7. For nomenclature in this SOP, all left, right, up and down descriptions are based from the shooters position as if the mag were in a rifle.

& 8. Once you get the magazine adjusted to fit your rifle, it should never have to be adjusted again.Depending on how tightly you have it adjusted, it may not however fit other 10/22 rifles depending on the receiver of each rifle.

9. If you over adjust the mag and have it too tight in your rifle, its possible to push the mag so far down that the bolt will not even pick up the round in the mag and will glide over it only scratching the bullet.

10. Some degree of play is advantageous and your initial adjustments should incorporate some play.The ability of the mag to wiggle in the gun somewhat will compensate for other factors and allow it to work.

11. Some “match” barrels are much more difficult to adjust for do to the lack of a chamfer or lead-in ramp for the bullet. Ruger factory barrels should all work fine.

Your TI25 magazine can easily be adjusted to fit your firearm using the following steps:

1. Remove the magazine from the firearm and ensure that your firearm is not loaded. Do not attempt to adjust the magazine using a loaded firearm.

2. Remove the barreled action from the stock by removing the barrel band and the single screw securing the receiver per the manufacturer’s instructions. The action must be out of the stock so that you can easily visually verify the position and contact of the adjustment screws on the receiver.

3. Screw all four screws down for clearance.DO NOT torque them down hard.You will strip them or break them off resulting in an un-usable mag. Be advised, that we will not replace mags that have been abused including breaking screws. Once the screws stop on their downward travel, stop.

4. Place the mag in the receiver.It should be wiggling left and right as well as front and back.You should have considerable play in all directions.

5. Our first adjustment is the ejector to the bolt distance. If you lightly push the bottom of the mag to the left, you can force the ejector on the mag against the bolt (which is too far).Correct adjustment is achieved by unscrewing the screws on the left side of the mag to make them taller until the ejector is in close proximity to the bolt but not touching. You do not want it to touch or drag on the bolt at all.You need some clearance between the two.Visually observe the screw heads against the receiver and make sure that BOTH are in contact with the receiver, and not just one.

6. Now when you lightly push on the bottom of the mag to the left, the screws should stop the travel before the ejector on the mag contacts the bolt, and there should be some clearance. Hold light pressure on the bottom of the mag and look at the right side. There should be a gap between the receiver and the magazine adjusting screws. Adjust the screws on the right side up until they are each about .003 from the receiver. You can use a piece of paper as a feeler gauge to set the clearance between the screws and the receiver.

The mag should now have minimal wiggle left and right and all four screws should equally be in contact with the receiver. Especially for your first adjustment attempt, do not try to adjust the mag so tightly in the receiver that it has no “wiggle” or play at all. Adjust using the .003 gap described.

7. The next adjustment is feed angle.Using dummy testing ammunition (available from Brownells), load 5 rounds into the mag. On the last round, put a small black El Marko dot on the back of the brass case at the 12:00 position. Insert the mag in the gun and chamber the first round.Manually eject it and observe the any scraping or scratches on the bullet or the case which will be indicative of possible adjustments.

If the bullet feeds well, you’re done. If it jams on feeding, you will have to adjust the feed angle which is easily accomplished by moving the two front screws up or down and moving the 2 rear screws the same amount in the opposite direction. For instance, if you want to increase the feed angle, take the two front screws down and the rear two screws the corresponding amount up. Adjustments should be in SMALL increments and all four screws have to be in contact when you are finished.

We have not yet found any factory unmodified Ruger 10/22 that the TI25 mag would not feed based on the mag's available range of adjustment. The TI25 mag adjustment range exceeds the total range available from any other after market high capacity magazine that we've measured.
