Very strong wrench - have gone up to 80 ft-lb no problem

Written on Jul 13, 2025

Great for standard AR15 barrel nuts or nuts for PRI handguards. Very strong have taken on and off barrel nuts up to 80 ft-lbs with 3 ft breakers and there's 0 sign of deformation or fatigue. Of course since this has 5 engagement points it has to be able to fit on over your barrel, so mostly likely you will need to remove muzzle device and gas block to use.

Clone correct, needs fitting

Written on Jul 13, 2025

This set screw version of the G1 FSBG is "clone correct" for an SPR-A and to-spec for a Mk12 Mod0. The con is these are fairly poorly made. The main bore is undersized and not finish reamed or deburred, they will not simply slip on to a normal 0.750" journal out of the box, you will need to ream or hone for fit by yourself. The front face of the lower cast portion sometimes has a noticeable draft angle, this doesn't effect function but looks sloppy. And of course you need to mill flats on your barrel to use this version.
