Compensators affecting bolt/barrel life?

[markm]

The Battlecomp would push down pretty good in rapid fire on a short barrel. That's the first muzzle device on an AR that I could really feel.

Not going to weigh in on whether it has a detrimental effect, but I imagine it would have to be at full auto pace to make any impact.

I didn't get to see the video posted, but if the A2 has a real "comp" effect, I'd have to say that the issue is not a big deal just based on the millions of A2 flash hiders in use for decades.

A shorter barrel will have more of a comp effect since the gasses at muzzle are higher pressure. On a 16" barrel, who knows. Now I wish someone did the same thing but with a Warcomp, just out of curiosity.

There is obviously going to be a natural amount of elasticity with the steel and if kept within limits would have no effect, I just don't know if the Warcomp falls into that category.

But a shorter barrel produces less leverage on the fulcrum which even it out somewhat. I bet Lysander could probably tell us on how the offset would be based on the decreasing gas pressure as leverage increases with barrel length.

But wouldn’t it take less pressure to bend a longer barrel? Leverage and all that…

Even if a barrel is in a "whip" wouldn't the upper (and thus the BCG) remain in line with the barrel extension and make the effect negligible to the bolt lock up?

It really mostly depends which direction the vertical grip is facing, but we all knew that already.

This is my thought. The receiver would need to bend in order for any uneven load to be placed on the bolt.

No one has even stopped to consider what effect the grip screw has on all this. Probably the key to unraveling the whole thing.
