Armalite or Rolling thunder comp

[apetrulis01]

Looking to build a new upper with a 13.5 inch barrel and a pin and welded comp. Question is which comp would be better, Armalite tunable or the rolling thunder? 

 

Thanks,

On a barrel with a pinned comp, I would probably prefer to use a comp that does not use a high pressure chamber before opening to the baffles. It fills with carbon and can eventually become a problem. On 16”+ barrels, I’d recommend removing the comp and cleaning that chamber out every 3-5000 rounds depending on powder used.

 

As for effectiveness, those are two excellent comps and both can be adjusted/tuned for vertical and lateral movement.

The new JP 3-port compensator is very good also.

As stated above the Rolling Thunder needs to be removed for cleaning, also it is made of stainless. That may limit your welding options. Beyond that, one of the best if not the best comp on the market.---------------Larry
