So the other day I was thinking to myself, "We sure had a bunch of cool toys at the last NorCal meet/shoot." This realization brought me to a hunch that between Robocop, Bubbasks and I we've got to have a bunch of .308 AR muzzle devices too. It turns out our cache consists of a JP Cooley brake, Bad-Ass Battle Comp, PWS FSC30, Griffin Armament Flash Comp, LMT A2 Comp, and Knight's Armament MAMS. I naturally wondered how these various devices compared to each other and flew off to YouTube to see if anybody had done a mass .308 AR muzzle device comparison like so many have been done of their little 5.56mm brothers. To my surprise, nothing this extensive existed (although Vuurwappen Blog's side-by-side is a damn fine benchmark).
Cue, ".308AR Productions."
This Saturday Bubbasks and I (and Robocop in spirit) will be filming a muzzle device comparison with our slew of toys. Below is the test plan. Let us know if there's something else you want to see!
Rifle:
-Stock LMT MWS 16" CL (Bubba's LR308 is too damn heavy to shoot standing all day and my PWS has a dead-blow buffer and is a piston system that might not replicate the common DI case).
Test 1 - Standing Muzzle Movement:
-Side view of standing and unsupported shooter.
-Three to five rounds fired in slow succession letting the muzzle come back to the neutral/resting position.
-Three to five rounds fired in rapid succession.
-Concussion blast masochist observer 10ft away at a 30deg angle back from the muzzle's face.
-Observer will have dB meter to record max sound intensity with each device.
-Shooter and observer will note performance properties of muzzle devices (muzzle movement, recoil, concussive force, and sound pitch).
-Video will be shown at full and slowed down speed (unfortunately can't do too slow since only have 60fps camera).
Test 2 - Rotated Muzzle Movement:
-Shooter will be crouched leaning to the side or lying on side as if shooting around a barrier.
-Camera will observe debris blown off ground by muzzle device.
-Three to five rounds fired in slow succession letting the muzzle come back to the neutral/resting position.
-Three to five rounds fired in rapid succession.
-Shooter will note performance properties of muzzle devices.
-Video will be shown at full and slowed down speed.
I'd love to add a "Test 3 - Flash Suppressing Performance," but I won't have enough time to stick around to film it this weekend :(.
Ideally, we'll be able to get through both tests this weekend, but there's a chance we might only have enough time for the first one.
