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 low profile gas block with straight gas tube.
The MRP-H QUAD 12.75 monolithic upper receiver for large caliber rifle platforms. Utilizes two locking lugs to secure/remove any larger caliber LMT barrel. This includes: 7.62×51 NATO, .243 Winchester, .260 Remington, 6.5 Creedmoor, 7mm-08 Remington, and .338 Federal. Barrel not included.

It’s hard to beat a monolithic upper. LMT does it right.

First off, by far the best customer service and user experience from the Sweatshop! Prompt shipping and great prices with even better sales!
Now the upper its self, typical LMT quality everything is tight, with great craftsmanship. I love these quad rails because you do not need to remove any accessories if you are swapping out barrels which I do periodically switching from a 20″ to 13.5″ depending on my mood that day. The barell change system is easy and incredibly sturdy have had zero issues with accuracy between barrel swaps. Now these aren’t precision bolt guns but for gas operated rifles they have great precision for my liking averaging between 1.0-1.5 moa which is more than capable for the role these rifles occupy. With handloads I have gotten 5 round groups in the .5moa range but that is by far not a deal breaker for me!
Lastly, its a quad rail looks sexy and gives +1000 internet points!
Thank you Sol and the Sweatshop for another great purchase!
