The gas system may be self cleaning to some extent but every time you shoot it it's dumping carbon into the trigger assembly which eventually leads to badness. This is particularly bad if it's suppressed. I learnt this from experience thinking that I only had to clean the gas system and then having trigger issues.
What kind of issues? I ran god knows how many thousand rounds suppressed and unsuppressed over a RRA lower without cleaning and it never once has failed me. I recently replaced the trigger with a drop in single stage unit, the lower is absolutely filthy.
Pew pew, subs are fun

Here is my Lower with the 30 BRX upper on it.

As mentioned previously it shoots pretty well, yesterdays efforts.

Todays efforts, not really "on it" today.

Still have some work to do on the 338.
Short fat seems to be the way to go to cheat more power out of the standard pattern. Those are pretty impressive results Greg. I've often wondered how much merit there would be in designing and "intermediate" AR pattern. One that didn't have the size and weight of a large frame, but gave a longer magazine to develop nice effecient intermediate rifle cartridges that would give rounds like the 6.5 Grendel a bit more clout. I reckon if done right with smart cartridge design it could make both patterns obsolete.
Like that 22 Grendel or the 6.5 brx? Neat stuff, going to do a bit of reading.
@Nick-D, what load are you running for that ?
I put a 3lb timney mine and after about 1k rounds started getting doubling. Took it back to the gunsmith and he said you need to clean this thing by flushing the trigger out with solvent. Carbon build up on the trigger sear had dropped the trigger weight to a measured 2.5lb which coupled with holding the gun loosely (i was shooting prone of a bipod uphill at rabbits) lead to the doubling. The amount of carbon blowing back into the action is much much worse on a suppressed ar and this is why the standard milspec trigger is six pounds.
