Nice build. How is that Dynacomp? How is it compared to a Battlecomp?

Thanks :slight_smile:

I have only had this out once, approx. 100 rounds, before this post.
I have never owned/shot with a BattelComp equipped rig, so I can’t compare, but from what I have seen/read the ST DynaComp Extreme is comparable to the BC.

BattleComp 2.0 vs ST Dynacomp - Recoil

fwiw:

  • I thought I’d try this brake out as I’ve always liked multiple vented/ported brakes in the past, like the VAIS. Also, I’ll probably shoot this occasionally indoor was well and didn’t want a side port brake, trying to be a good neighbor :D. If I swap this, it will more than likely be back to the A2 FH or a AAC FH.

The ST DC Ext. Short performed as advertised, Reduced “Felt” Recoil, easy to stay on target without any major upper body control input. Felt like a “slight” thud/push back, Need to mention to put in consideration of the AR15 operating system, to add to this “felt” recoil.

By no means is this a “Flash Hider” or does Spikes Tactical advertise it to be, its not. You could clearly see the blast lighting up the lane I was in at my local indoor rifle range. More of a distraction to others than myself while I’m behind the sights. I sure wouldnt want to shot this setup in low light.

I have shoot a similar setup with a SureFire MB556K Muzzle Brake and I liked shooting it outdoors. Gun didnt move and seeing impact standing at 300 was nice, but was turned off by the concussion indoors, went back to an A2 FH.
I guess time will tell if I keep this or go back to a FH.

Very nice, that set up is sick. I like the long handguard while keeping the pinned fsb. Looks like a solid rifle!

5

Very nice. I like it. How did it shoot those 100 rds. Did you get any groups?
