These are adapters that will allow the use of standard upper AKM handguards to be used on a Tantal/Beryl style rifle. Simply slides on over the gas tube and fits into the rear sight block. Once your handguard is in place, the fit is very solid.
Solid CNC aluminum.
Note: As is common with AK parts, this part may require fitting.
We tested the fit and while this adapter dropped right into a rifle without a gas tube, after mounting it on the tube it did need some minor filing. Additionally, your handguard itself may need some fitting, as upper handguards have a lot of variation. The Romanian Wood upper pictured did not need modification, but others did.
