I've had this BCM barrel sitting around for a while. Had it in an Aero upper but their tolerances weren't very tight. Barrel slid in with no resistance. I shot it a few times and it was all over the place for accuracy. BCM had a sale on their demo/blem uppers last week so I scooped one up. Friend of a friend recommended Stinger Supreme for a Handguard. Small family owned company out of Texas. Rail showed up today and for the price it's pretty nice. Anodizing is consistent and the intergrated rails are nice. 3 QD ports built right in and the Keymod slots are machined correctly. Seems solidly built. I'll update after shooting it.
All done. Took me a few hours to get the barrel in. When Bravo Company says they machine their uppers to be "snug" they're not lying. Ended up lapping it. Rail had a little play in it when I first got it on. Added one of the shims and its tight as can be for now. The integrated rails are really nice and machined well. QD slots accepted my BCM, Troy and VLTOR swivels. I'll be interested to see what kind of accuracy the barrel and upper are capable of. I'm happy with the results so far.
