AR Barrel Indexing Jig

DESCRIPTION

Take the guesswork out of barrel work. Whether you’re drilling a gas port or cutting flutes, getting the barrel indexed precisely is the difference between a clean job and a ruined blank — and this jig makes it simple.

Insert the barrel extension into the jig body, and the precision-machined notches give you accurate, repeatable alignment for 6-flute and 8-flute patterns, as well as gas port location. No layout dye, no measuring twice, no hoping you eyeballed it right.

Compatible with both AR-15 and AR-10 barrel extensions.
