I have no use for another 11.5 upper, but that's awful tempting.

^^^^^^^^^^^
Is the MK2 gas mitigation worth the $20 extra bucks?
Though I am not a huge fan of the 9” handguard would prefer the 10” but those are out of stock.

However this vacation is currently sucking away all my fun money.
It’ll be a bit before I’ll be ready to buy at this point.
Also want a dedicated 5.56 can which I kind of feel like buying first and use my 16” Aero until I SBR the lower and get the 11.5”.
Then of course I kind of feel like waiting to see if the engraving rule for making SBRs goes away.

I have a BCM Mk2 upper and I'm not sure I can tell a difference. But I run a Surefire non-flow through can, it's possible the Mk2 mitigates more gas with a flow through.

I’ve shot a couple of our MK2s. They have the Radian SD Raptor charging handle. We have Surefire RC2s and Dead Air Lazarus. The set up on both are less gas than a standard upper.

I have the standard 11.5 upper with a Lazarus. Shooting hard I occasionally get a whiff of gas. The MK2/SD combo seems better.
