Resist extreme temperatures and erosion from super-heated gasses and particles.
3.
Redundant welds
Means no parts loosening due to extreme heat, impact, vibration, or hot/cold cycles; eliminates crack propagation inherent with continuous circumferential welds.
4.
Fail-safe baffles
Designed to allow an unbalanced or defective projectile to pass through the baffles, thus minimizing the chance of it exiting the side wall so it continues downrange.
5.
Minimal weight and length
Increases weapon maneuverability and stowability; reduces carried weight.
SureFire's Fast-Attach SystemNow Improved
The original Fast-Attach system has been improved in three distinct ways. First, the locking ring surface is over one-third wider for a better grip during attachment and detachment. Second, the locking lever itself is stronger. And third, the locking lever is now surrounded by a raised section of the locking ring, reducing the already remote possibility of accidentally releasing it. Individual parts of the Fast-Attach mechanism are easily replaced in the field by a soldier or armorer. Suppressors with the improved Fast-Attach mechanism are backward-compatible with existing SureFire suppressor adapters.
Targets show typical results when SureFire suppressors are attached to a firearm: minimal shift from firearm's point-of-impact in unsuppressed mode, and improved group size. Firearm used: Remington 700 in 5.56X45 mm, 16" barrelwith SureFire MB556K muzzle brake adapter. Ammunition: Black Hills 77 grain BTHP. Range: 100 yards. Center square:1" x 1". First target: 5-round group, no suppressor. A different SureFire FA556-212 suppressor was used to shoot 5-roundgroups shown on remaining targets.
SureFire offers two types of Fast-Attach® suppressors:
END MOUNT
Our End Mount models extend slightly or not at all beyond the rear of the muzzle threads.
OVERLAP
Our Overlap models overlap the barrel about 2.25 inches beyond the rear of the muzzle threads.
Both types meet the same rigorous testing standardsoutstanding accuracy, zero or minimal point-of-impact shift, combat-proven durability, and rock-solid attachment under abusive conditions. Some users prefer one type over the other, so we make both.
