AR-15/M16 MIL-SPEC BUFFER TUBE Reviews & Ratings

Receiver extension tube has the correct, 1.146" outside diameter for mounting collapsible buttstocks designed for the smaller, mil-spec tube. Lets you mount a mil-spec stock on a civilian carbine or convert a rifle with A2-style fixed buttstock to collapsible configuration; carbine action spring and buffer assembly required. Allows fast, easy repeatability of buttstock position with five notches on underside to accept the stock’s locking pin and corresponding white position numbers on top visible through the witness hole on many stocks. Precision machined from aluminum bar stock for consistent dimensions that ensure smooth, snag-free sliding of buttstock.

SPECS: Aluminum, hardcoat anodized, matte black. 7-3/16" (cm) long, 1.146” O.D. 7075 T6 Aluminum

Vltor Mil-Spec Receiver Extension

Used on Arsenal SLR-107R in conjunction with Rifle Dynamics AK-47 M4 Stock Adapter, Titanium AR-15 QD Endplate & Castle Nut Combo and Rogers Super Stock. Much more pleasant to shoot than original stock. Nothing detrimental compared to rifle's original configuration regarding this part.

Not Vltor at its best

Ordered one to be used in a carbine with a Magpul CTR stock. The stock wobbles significanty more compared to D.S. Arms extension. This was a huge surprise because Vltor has a premium brand reputation. It works ok and coating is excellent.
