10. Muzzle Break

. (M40A5 Only) - The muzzle break (26) is attached to the weapon’s barrel (14) for the purpose of pro-

viding a mounting point for a sound suppressor (28). The bearing surfaces and interface notch on the muzzle break pro-

vide a highly precise fit between the suppressor and the muzzle break. The muzzle break also incorporates a flash

suppressor (27) to reduce muzzle flash of the weapon when the suppressor is not being used.

11. Sound Suppressor

. (M40A5 Only) - The suppressor (28) is a lightweight, quickly attachable/detachable unit that is

designed to reduce both the audible report and muzzle flash of the M40A5 weapon when fired. The suppressor is made

of high temperature alloys and stainless steel. The suppressor fits over the barrel muzzle break (26) riding on bearing

surfaces that provide a precise fit. The suppressor then locks securely into place by use of a locking ring (30) equipped

with a ratchet stop (29).
