fouling with a short gas system.

[luckyguy1]

I am planning a fun project and I have a question.

I am building a 11.5 inch barrel AR15 5.56 with a pistol length gas system, adjustable gas block, and a suppressor. for reasons more technical than I want to bore you with.

my question is, will the gun experience increased gas fouling or unburnt powder in the gas tube due to the short gas tube and the added back pressure of the suppressor relative to the short barrel?

is there a potential reliability issue beyond the other factors of mechanics?

and if it looks like I might, what would be a recommended powder or loaded ammunition that would help mitigate the fouling?

Thanks.

... Why a pistol gas system?

older ciener suppressor.

it sleeves the barrel back 5" from the muzzle. regular gas system would be in the way.

it's an old, heavy design but very quiet, and it's mine and I don't have to spend more money on something new with all of the added hassle from ATF.
