NOTE: This handguard's top rail will only mate up precisely with DPMS's new production Low Profile A3 Uppers. To determine the type of upper you have, remove the charging handle and bolt carrier group, then measure the thickness of the receiver's top rail where the charging handle is installed at the rear. A new Low Profile receiver will be 1/8" thick, while the older High Profile receiver will measure 3/16" thick. This handguard may be used with an older high profile upper, but the top rails will not match up.
