Welcome Troy...love the stuff you're making that nobody else is (these, AR70/90 and SAR-80 parts, etc).

Pics hosted from the email Troy sent me:

It is pictured on a 551LB, which has the same profile as most 553LB guns. Some LBs have a NATO hider though. Does your gun have what look like wrench flats behind the hider?

Yep

You can use a Griffin M4SD. Maybe a Gemtech Halo too; if a Halo works, so will the Griffin A2 adapter for HUB threads in other cans.

I was thinking the same thing.
