Re: Question shooting a suppressed ar-10 carbine
Same answer as the ones given in your previous thread about removing the permanently pinned Armalite muzzle brake.
It will get MUCH dirtier MUCH faster with the can installed. It is the nature of the beast (especially with a DI gun) and there is no way to avoid it. In terms of HOW dirty...it is difficult to quantify, but I can tell you it will depend on the ammo you are running, the specific suppressor you are using, etc., etc.
I seriously doubt you'll be able to get 500rnds through it with the can installed before you experience the need to clean it (at least partially) or lube the hell out of it and hope she keeps running.
Also, don't forget that you MAY need/want a heavier buffer depending on the ammo you are using as the can will increase the pressures which in turn increased the amount of general wear/tear on the rifle, broken bolt catches, etc., etc. A heavier buffer will help to slow things down a bit and "take the edge" off. You can achieve the same results with an adjustable gas block (in combination with the heavier buffer or by itself). You also may want to invest in a Gasbuster charging handle or take the RTV route to prevent getting hit in the face with blowback.
