The gas system is adjustable at the block
A RIFLESPEED gas control lets the rifle be tuned to the load and to a suppressor, rather than being fixed by port size at manufacture. The gas block is pinned to the barrel, in line with the Bombproof by Design™ philosophy: a pinned block cannot shift on the barrel the way one held by clamping or set screws alone can.
The brake comes off
The Faxon Gunner 7.62 MuzzLok® brake is held by a MuzzLok nut, not a crush washer, so it can be timed and removed in the field. With it off, the 5/8×24 thread takes a direct-thread suppressor.
The camouflage is applied by hand
Receivers, handguard, buffer tube, stock and grip are Cerakoted in chocolate chip by hand, so the pattern on each rifle differs from the one photographed.
* A note on the name
SOTM5 names the rifle; the serialized part is the lower receiver. MOD-0 names the thermal-fitted billet upper. The serial number on the left side has been blurred in this photograph; no other marking has been altered.
