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!
