Suppressors AAC Cans with indexing marks question scar h sprm4

Re: AAC Cans with indexing marks question scar h sprm4

The index markings were meant to be used for STARTING your threading. i.e. Index off of the gas block . . . orient the can with "2" in line with the gas tube and turn clockwise until it stops, then turn counterclockwise and pull towards muzzle as outlined in their manual to confirm it is lock in.

Never had a problem.

Right

For my SPR/M4, I put the 5 in line with the gas block and screw it onto the mount. Once it is tight, the 5 is two clicks beyond the gas block, so for mine I use the 5 as the starting point and ending point.
