-The dimensions match up with the standard bird cage so suppressors that use the A2 will work on this. As will blank firing adaptors.
-Helps with muzzle rise vs the A2
-No where near as much side blast as side ported brakes/comps
-Stainless steel construction.
-This is the standard size (Mod 0) but the Mod 1 is available to be used on 14.5'' pinned barrels to comply with NFA laws
-Retails for $90 +/- $10
-Less flash signature than standard side ported comps
-Not as much muzzle movement reduction as the Battlecomp (but it costs less than the Battlecomp). The recoil impulse feels like the gun wants to move a little right or left rather than up or back.
Here's a review with some day and night shooting, a side by side comparison of the flash signature with the Battlecomp, and a discussion of the pros and cons of the comp:
