Slim 9mm can or chunky handguard?
I am building out my AC Unity kit I got from the PSA deal last week, and I would like to tuck a 9mm can under the handguard. The problem is that the FTN is too chunky to fit under the handguard, which has an ID of 30 MM or 1.2". I was wondering if anyone knows of either a slim can that can tuck under the handguard, or a chunky handguard that can fit over the FTN, or a combination of both?
