Front Sight base, pins, sling swivel and handguard cap all off my BCM upper. I did verify that this is a .750 block. I did scratch the finish a little getting the stupid pins out but there is no functional damage.
** Edit **I will also throw in the BCM barrel nut and delta ring assembly I just took off the gun as well. As usual the pics look worse than they are, the parts all look near perfect installed on the gun.
