adding a suppressor to a sass .308

[snoopygw73]

I have a dpms lrt sass .308 and I am wanting to add an aac or silencerco suppressor to it. My question is this, do I have to adjust the gas block or add an adjustable gas block for it to cycle correctly. Thanks.

You shouldn't have to for it to work. It may be beneficial but isn't mandatory.

Thanks. I was just worried it might increase too much back pressure.

Most factory .308 gas guns already shoot over-gassed. Putting a suppressor on it will just make it even more over gassed and give you more blow back. It should cycle just fine but will be hard on brass. Like Lafsnguy said, it would be beneficial for tuning but you can run without it.

I normally leave my brass at the range anyway, I just don't want to damage the firearm.

My guess is overgassed bad and you will feel the carrier bottom out in the stock every shot.

You are also going to catch it in your eye from all the gas escaping, heavier buffer will keep the action from jarring your teeth and turning the gas system down for me would almost be a must. You buy a suppressor to be quiet and more pleasant to shoot but then sacrificing annoying gas puffs on your face and harder buffer slamming just doesn't make sense. Do it right, do it once and tune the gun properly for the suppressor.

I have the same rifle and it functions but it does over gas. I haven't started to look for a solution yet but I'm about to start. I tried my Thunder Beast 30-P-1 that I bought for my my 300 win mag and it over gasses bad on hot loads on the LRTSASS. Doesn't seem to hurt anything though. Blew out a couple primers. Take the suppressor off, no problems. That maybe more to do with back pressure than gas but either way the difference is noticeable. Like lots more smoke and noise in your face.

Buy this and just tune the rifle better, its all in the gas block pushing to much to the bolt. Also depends on your gas length system and dwell time.
