I thought there was a thread here about this, but didn’t see one.

I get the general consensus That ARs are gassy, well I’d like to “better” what I can and play with different CH’s. I get the silicone trick, but I’m skipping that for now..

So what ch’s you guys using that are an improvement in blowback

Are the raptor sds worth it over say a Geissele ach/sch?
