Finally pulled the budget together for the rest of my dream rifle build and am a bit torn on the muzzle device. This is going on a 556, but I do plan on getting 6MM ARC and 300BLK down the road including that I have a 22lr. Currently own 2 16" ARs. One that's a cheapo built and another ultralight.
Surefire RC2:
Pros: Flash suppression w/ and w/o the can, durability, trainers and blank firing adapter is a big plus, can use a 13.7 / 13.9" barrel
Cons: Blowback, weight (no TI option)
OSS:
Pros: Little to no blowback, weight (ti model), will work with non-ARs I get down the road (especially if I opt for the 762 ti can), less part wear due to little to no blowback
Cons: Would need to go with a 14.5" barrel, terrible flash from footage I've seen even with the flash hider models
KeyMo:
Pros: Can use a 13.7 / 13.9 barrel, widest options for suppressor and muzzle device choices
Cons: Weight (due to keymo adapter), blowback (depends on suppressor)
I like the surefire for the flash suppression, but would likely be a dedicated 556 can only for ARs, but the trainer and blank firing adapter are great for training. OSS is really appealing for the decent flash reduction, can use it on more than just an AR and low impact parts due to less blowback, I see myself getting the 762 ti can. KeyMo is extremely appealing because I wouldn't be married to one suppressor and have a lot more options for muzzle devices, IE I could get my favorite muzzle device and then decide which suppressor(s) I like the most.
