    BCM Comp Mod 1

    Ok, so it showed up today and I happened to be off...

    These are quick and dirty iPhone 5 pics, bear with me.






    So I was running a PWS FSC556 (actually a KAC556 so I could mount a QDSS suppressor at some point).

    I installed the BCM (no pin) on my 16" barrel and went out back to test for concussion and muzzle rise. I'll probably use this on my 16" gun until I get a 14.5 middy barrel or a Mod 0 is available.

    I tested this quick and dirty as I have not re-checked zero on the gun; close range fast shooting. I tested for concussion by standing beside my fence so I could gauge my concussion as compared to the PWS. I was alone so I had no one to stand beside the comp and gauge true blast/concussion.

    RESULT: Subjectively, I can feel about 40-60% LESS blast/concussion than the PWS. I think this is significant if using in CQC or carbine class applications as well as small shooting bay competition.

    I tested for muzzle rise by trying to keep the dot as solidly in the same place as I could with single, double, trip and quad tap shooting as possible; again close range, quick and dirty.

    RESULT: I felt like the dot moved less than it did with my PWS. Now, admittedly the blast from my PWS was so objectionable, even in the open, that I found myself noticing that even when I was trying to focus only on the dot. The dot seemed to move less with the BCM, especially the more rounds I fired in quick succession.

    I am in the midst of changing the setup on my carbine so the AFG was off and the LaRue FUG was in to be DuraCoated so I was getting a good grip on the SCAR panels on the HG. This was fine with me as I shoot my 1873 rifles super fast locked down in my shoulder in this manner; I'll be interested to see if it changes when I get my FUG back on the gun!

    I guess this is similar to the MSW Review here:http://modernserviceweapons.com/?p=1047

    The only regret that I have is that I do not have a BattleComp to test it against.

    There you go a raw, super quick and dirty test. I know some of the pros on here will do a more thorough test and I am waiting with breathless anticipation of them. Until then, this was something y'all can refer to from someone who is definitely not a pro on here!

    Enjoy!

    Unfortunately no BC experience to compare. I was getting ready to buy one to try when the BCMs started becoming rumor so I waited. The MSW review does compare it to the BC; see the link above!

    Thanks.

    Thanks for the mini review!

    These have caught my eye, since they advertise that they work with A2 mount suppressors.

    I've also heard that they really help mitigate muzzle blast... I need to find one locally to see for myself, I suppose I could just drop the coin on one though.

    Not only was I concerned about which brand of phone you used, I was also wondering which version. Thank goodness you told us.

    Thank you for sharing. My next upper will have the BCM comp. The video was also great.

    I love my Surefire brake. Not sure why I get all the dirty looks
