PT-1/PT-3 Stock Adapter (4.5 mm)

The adapters are designed for attaching PT-1 and PT-3 stocks to rifles which have folding rear trunnion and use an axis pin diameter of 4.5 mm ONLY (ex: Arsenal SLR104FR/SLR107FR or AKs-74U pattern)

Note these adapters securely lock the stock in the extended position, but do not include a mechanism to lock the stock in the folded position.

NOT COMPATIBLE WITH FIXED STOCK REAR TRUNIONS OR RIFLES LIKE THE KR103 or KR9, WHICH USE 5.5 MM AXIS PINS.
