The 13.25" M-LOK upper receiver is cerakoted FDE from the LMT factory.
The receiver and handguard are made from a single piece of aerospace grade aluminum. The barrel is held in place with a proprietary locking system that utilizes two locking bolts accessible from the right side of the receiver. The only tool needed is a standard T-30 Torx bit to tighten the bolts.
This receiver requires the patented LMT monolithic barrel assembly which has a pinned low profile gas block with straight gas tube. Or you can send your non-LMT barrel such as a hodge, criterion, or other favorite brand to D.Wilson where he can modify it to accept the LMT Proprietary barrel nut. https://www.dwilsonmfg.com/LMT-MRP-Barrel-Conversion_p_12.html
