Spikes Dynacomp or BCM Gunfighter Comp

Spikes Dynacomp or BCM Gunfighter Comp, Which one???

2

I’m local to spikes and they told me that the Dynacomp had a serious issue with hot gas erosion and eventual structural failure of the ports surrounding the blast chamber. I do not know if this was ever fixed.

BCM Comp

3

Never shot a BCM comp but I have shot the Dynacomp along side a battlecomp. Couldn’t tell a difference between either really accept the dynacomp had a larger flash signature. If it were me and my only two choices were the BCM or Spikes I would try the BCM.

I ordered a BCM, was thinking about grabbing a spikes for another rifle and trying both. I have a Daniel Defense Climb Mitigator I am getting ready to sell and wanted something else to try…

5

I got a BCM Mod 1, the movement seems more lateral to me. Going to the range today so I will get back and report.

6

If you want to try a different device on another rifle, I recommend trying the Griffin Armament M4SD II Flash Comp.

7

+1 on that, works like my battlecomp & I have fired a spikes before also.

I second this. For me it was the best overall between the BCM, Spike’s, and Battle Comp. Another positive about the Griffin is that is is suppressor compatible with their excellent M4SDII suppressors.

If you are stuck on either the Dynacomp or BCM Comp then I prefer the BCM. The spikes threw too much flames and was a bit louder as well.

I as well would go with the Griffin Armament comp, I have found it to be excellent. However, forced to choose between the Dyna Comp and BCM I’m going BCM. For my tastes the DynaComp is rather hefty and throws quite a bit of flame and concussion and I personally am not aware of the qc issues. BCM is generally always GTG.

I just read up on them, I am going to pick one up, thanks.

I love my Spikes Dynacomp

Here’s my BCM comp. Its very soft shooting, almost no felt recoil. The movement you see in the video is the rest moving forward. There is some considerable lateral concussion though, its not fun shooting next to it.

yes

The Dynacomp is a GOOD compensator. Better for compensation than the Gunfighter(IMO). Like the BC, it sucks or flash.

Another vote for the Griffin Armament M4SD II Flash Comp. Best multifunction comp I’ve tried. Spike’s Dynacomp is OK but doesn’t seem as effective or look as durable. Haven’t tried the BCM comp. Between Spike’s and BCM I would go BCM.

15

Has anyone tried the brakeout 2?

16

I have the BCM Gunfighter comp on my HSP “The Jack” carbine. Combining the 14.5" mid-length gas system, the comp, and the properly weighted buffer and spring, it is an incredibly soft shooting AR. I mean really, really soft shooting.

17

I have the BCM Comp 0 on a new upper I just built. The barrel is a med length so shooting it does seem softer compared to the standard A2 on my other carbine length upper.

I might as well just copy and paste this from the other thread that is going on about a BCM GFC;

Keep in mind, that the BCM Gunfighter comps sacrifice part of their stainless steel construction within itself. You WILL see pitting and some discoloration over time, and that’s normal. I saw a picture of a well-used BCM GFC that was pitted and had a green discoloration to it…which is totally normal.

[i]"The combustion gasses exiting the muzzle of a rifle are extremely hot, traveling at extreme velocity, and contains not only burning gasses but solid particles of unburnt powder as well as metals from the projectile. Due to the inherent nature of steel, it is nearly impossible to survive unaffected in this environment when directly exposed. The high temperatures begin to make the steel more malleable, which allows solid particles and pressure waves to deform and erode surfaces upon exit.

Due to the new and unique design of the BCM compensators, the user may notice small pits on the interior surfaces of the compensator. This is normal. Most designs do not impede the exit flow very much, while the BCM approach is exactly opposite. These surfaces are specifically designed to operate within the environment found at the muzzle, and are intended to allow significant amounts of deterioration before any loss of performance is seen/felt. These compensators have been tested through many thousands of rounds, and while the wear surfaces may give pause to some users, trust when we say that it’s normal."[/i]
