Or run a similar set up with gas reducing block and BCG? I just received both pieces and getting ready to add them to SBR i shoot regularly. I am shooting a 10.5" BCM build running a Griffin M4SD can. Shooting a mix of factory ammo, no reloads...

Just wondering if anyone has run a combo like this to reduce gas back into the receiver/magazine/face, and if both together might take off to much gas. Thanks in advance for any input.
