Does this upper have that burnt finish on the handguard or is that just the picture?
Carson T on Jul 30, 2018
BEST ANSWER: Must be the picture. Mine is the common, flat black finish so familiar with every AR-malite platform I am familiar with, along with the M16a1 I carried once upon a time.
Is there enough clearance at the end of the rail for a suppressor?
John G on Jun 2, 2018
BEST ANSWER: depends on your can. I made mine using form 1, thus was able to turn in a lathe to make it fit. I would say yes, with modification. The rail is super quick to remove/install so go for it! keep the gas block tight
