Down vent and sand cut BCG and gas stopping charging handle

[RussSurfs]

I am a lefty shooter and run an OSS suppressor (now HUX) on both an 11.5” and 18” BCM. Both run fine with the factory BCG and gas block. I think that is partially the suppressor design. A dirtier magazine for sure, but I really only notice the gas if shooting indoors.

The flows are gas system agnostic. Pretty happy with them on serval different platforms.

Rdb is perfect for a can. 32 position gas block, factory. Piston. Down, rear ejecting. Ambi. Nothing to tune or buy. Fixed scope rail no loss of zero upon disassembly, cleaning. I'm a left shooter and know the joy of getting gas and bits in the face, sucks. Or catching a hot shell in the crook or your elbow.

I had a lot of issues trying to tune my ADM 14.5 with the OCL Polonium (probably the highest backpressure can I've ever owned). A 3-5 shot string would have my eyes watering pretty good. A BRT dedicated suppressed gas tube and KAK downvent BCG have pretty much cut it down to nothing.
