    This product is outstanding. The fit and finish are perfect and the tutorial video made installation a breeze. I opted for the shorty version as I don’t use a ton of rail space.

    Customer service is great. Very fast shipment. Don’t anticipate having to contact them for anything else, until I order another one for my other SCAR. Great product from a very good company. They deserve your support and I look forward to whatever else they may have up their sleeves.

    I liked this system so much that I couldn’t wait to buy my second one. Everything I noted about the first one was once again true. These guys are definitely consistent.

    The MREX 4.9″ system totally transformed the feel of my SCAR-16. Even though it adds a tiny bit of weight, the additional purchase you can obtain allows you to maintain a better balance of the rifle in the shoulder. In my opinion, it actually feels lighter. The MLOK system is outstanding (I was a keymod guy prior to this) and the finish is beautiful and blends nicely with the factory color scheme on my rifle. I am very happy that I didn’t purchase one of the extended rails from the other companies out there as they just don’t hold a candle to the clean feel and versatility of this system. The MREX is a must-have for every SCAR.
