I got a Silencerco Spectre II and a SpecWar 762 and I've been really been enjoying them.
I bought the SpecWar 762 to use on 3 rifles.
- AR-15 in 5.56mm (DI action)
- Savage bolt rifle in .308 (not threaded yet)
- Ruger SR-762 (piston action AR in .308)
The Ruger SR-762 also did well for about 80 rounds or so, at which point I started having problems in the action.
I noticed that there was plenty of filth blowing back into the action and the magazine, coating the next rounds and I suspect that this may be contributing to the action fouling up (which I was not expecting from a piston action).
Anyway, I was wondering if a suppressor generally causes enough backpressure to do this.
I am thinking that every so often I will need to wipe down the BC group and spray it down with CLP to keep things working properly. What do you all think?
Are there any other considerations I should be keeping in mind when using a suppressor in a semi-auto rifle with a high energy cartridge such as .308?
I am not convinced one way or another that the root problem is related to the suppressor usage. It could be that this rifle needs to run wet. Maybe the fouling in the action exacerbated it, maybe not.
I'm looking forward to your feedback.
