AR Buffer Tube Alignment Jig

Foxbat Machining 202.4KiB Released September 22, 2025, 8:05 PM 0.001LBC 0 Reposts
This tool aligns an AR style receiver extension (buffer tube) to the receiver so that the nut can be tightened.

There are two models. A "small" that works on small frame ARs like the AR15 or AR9 and a "large" for large frame like the LR308/DPMS and possibly AR10. The large also works on small frames.
