a slight thread hijack... do .300 blackout uppers also have to be HBAR to be legal in MD?
No.

I have that exact upper on a Spikes lower, and really like it. Lots of ammo thru it and not a single issue. With a 1x4 scope and 55gr handloads (Bulk Hornady SP) it keeps under 1 moa off sandbags.
It is HBAR, but I like the balance with the rifle-length handguard. Changed that out to a Magpul MOE.
Thanks all for the info...yes, I was looking at a Bushmaster HBAR upper...the Dissipator model...Midway and others advertise it as HBAR, but I can't find anywhere on the actual Bushmaster website to say one way or the other...s
