Geissele SMR MK4 Rev A 13" rail. This is one of the older MK4 rails, has different cutouts on the bottom part of the rail as compared to most. Overall in good shape. It has two dings…one on the left side near the rear qd socket, one on the right side about halfway down on the edge. Both touched up with alumablack so they’re a bit hard to spot.
$230 shipped in CONUS. Will consider a trade involving LMT enhanced BCG (latest gen), LMT MRP barrels, MRP chassis, Larue handguards, maybe mbus pro sights.
