If you want to get the full fun value out of your SIG Sauer .22LR 1911 handgun by being able to mount any 1/2x28 TPI threaded accessories such as a SUPPRESSOR, a FLASH HIDER from an AR15 or one of our UNRESTRICTED FAKE SUPPRESSORS, then this is the part that you need. This thread adapter quickly and easily replaces the factory barrel nut with no modifications to the pistol.
We manufacture 1000's of thread adapters for other firearm manufacturers, national firearm wholesalers, local retail gun shops and you, our internet customers. So, don't let our low price fool you about the quality. Our professional volume manufacturing capability allows us to offer you a precision machined adapter at a great price. Our Thread Adapters are CNC manufactured to precision tolerances from solid steel rod (NOT aluminum) in one CNC lathe operation to ensure exact thread alignment and are hot salt blued to match your firearm. Each retail packaged adapter assembly consists of one adapter and one knurled OD thread protector. If you don't yet have a thread adapter, you're missing the best part of the gun! Order one now!
