Thread: Understanding compensator nuances (observation of BC1.0 vs BCM)

    I wouldn't recommend a race type comp for combative use. The blast can... complicate things in confined spaces &/or create difficulties in proximity to others, and enhance ones visible signature.

    The latest induration of KAC's... MAMs does a pretty good job of mitigating the cons and while allowing the pros... and of course allows a muffler as required.

    For pure race use.. proper tuning, using a device, will consider; barrel length, rounds used, body/position type.. will find each shooter with their own favorites.

    A lot of brakes do different things as barrel length changes. Some go from pushing too hard, to neutral, to not pushing enough. Some hit a length that blast gets bad fast to loosing effectiveness at longer lengths.
    Personally, I hate the blast of open brakes, but they're normally effective for recoil control.
    I've been playing with the MAMS with good results so far on many barrel lengths.

Most shooters who first use the BCE and an aggressive grip on the forend with downward pressure experience more muzzle dip then others. I have actually ported the flat downside of the BCE for certain shooters who insisted on this modification. While I still use a "C" clamp or thumb over type of grip the BCE requires less down force or a more neutral grip and I have lessened the amount of downward pressure that I use which has been a benefit. I also run one on my select fire, 10.5". When I first transitioned to the BCE on this rifle the dipping was very pronounced on full auto fire. However I have learned to use a more neutral grip and the rifle does not dip with a more neutral hold even on a 30 round string of FA fire.

    As for the BCE vs the BCM comp, myself and 3 of my guys all experienced much more movement with the BCM comp. Movement of the Red dot is easily seen on an IDPA or IPSC target at 50 yards off hand shooting when comparing comps and this is how I like to non scientifically notice movement. For all of us on the IPDA target the BCE stayed relatively close to the -0 center circle and the BCM would push all the way off the target. The BCM had a distinctive and much more pronounced push and sideways bounce. Also as an open sided comp, it had much more noticeable side blast to include concussive impulse and particulate or debris kicking out to the sides. Now I have been accused of splitting hairs and many may not notice a difference in the two comps, but a very skilled and in tune shooter should without a doubt notice a difference when similar or the same rifle is run side by side or back to back. If you are looking for cost effective and a great comp, choose the BCM. If you are not afraid to pay a bit more, the BCE is a great choice. If you want a pure compensator or brake, there are better.
    I used the BCE extensively and transitioned to the BCM earlier this year. My experiences mirrored yours almost exactly, including select fire with the BCE. I found the BCE to be very controllable in FA. Once I changed my tension on the gun, a 30 round string could easily be kept in center mass of an IPSC.

    The BCM has a lot more lateral bounce, less of a fireball effect than the BCE, but throws more particulate. Sort of like a sparkler in low light. I'd really like to try the MAMS, but I just can't justify the cost. Ultimately, I may be headed back to a simple flash hider, especially on my SBR, as the tradeoffs of using a comp are starting to outweigh the advantages for me.

    Basically sounds as if everyone is accustomed to applying such an aggressive shooting style due to running standard flash hiders for many years. Once the transition to compensators occurs (specifically battlecomp) the shooter needs to remember that driving the barrel down is no longer necessary. The aggressive C clamp shooting style is still very effective for transitioning between multiple targets and controlling the remaining recoil however just less force applied downward on barrel end.

    In general layout, the Griffin Armament SDII Flash Comp seems to be very similar to the KAC MAMS. A guy had one at the last agency rifle class I took. I didn't get to shoot it. It had the low-blast traits of the BC's but kept the muzzle stable very well.

    It did not appear to have any muzzle dip as the shooter's stance was pretty aggressive.

    If it worked out to be a poor man's MAMS, that would be nice.....

    Anybody have one that can comment here?

    I've been curious about that one as well. I wonder how the muzzle flash compares to the BCM & BCE?

    in the daytime it was equal to my FSC 556 and every other A2 which is to say it had no flash. there was a Rainier Arms XTC there that did have some flash so it is definitely less than that.

    That's an interesting review of the Flash Comp 2. I'm really wondering how that stacks up against a MAMS as well. It would be very interesting to find out.

    I'd like to see a side by side as well, but there is very little info out there on the MAMS.
