These are 100% steel! Aluminum loosens as the rifle heats up because it grows at a faster rate. Beware of cheap copies!
This bolt-on lower handguard retainer is for the Saiga 410 shotgun. Installation of this retainer allows your shotgun to accept regular AK lower handguards and cleaning rods. This part allows you to avoid having to press off the gas block and cut the locking lever notch in the barrel.
This pic shows the retainer installed. Install is simple, just tighten the two cap screws after the handguard is on and you are done. There are also set screws to keep it from sliding forward on the barrel.
This pic shows the retainer installed with a Galil-Style handguard.
Use of my Press-On Upper Assembly will allow you to use unmodified AK upper handguards. It's a great way to add U.S. made handguards for one additional compliance part.
