    I ordered the ARJ-M1 receiver sets and they shipped very quickly. They showed up well packaged and look amazing. They fit together tight with no play between the upper and lower. I haven’t had a chance to build one out yet, but they appear to be high quality and are hands down one of the best looking receiver sets I’ve ever seen.

    Super awesome receiver set, everything is made easy to put together and there’s zero play between the two receivers works great and they look absolutely phenomenal

    This receiver set is one of the finest billet receiver sets I have ever had to work on. Everything fits perfectly no slop between the upper and lower and the threaded roll pins make putting the bolt catch and forward assist a breeze. No more messing around with those roll pins that always get lost when you’re trying to drive them in with a punch. These products are light and are of the highest quality I have ever worked on. I personally have seen there manufacturing facility and I was very impressed with the attention to quality control to make every single part to mil-spec and beyond. I will be a customer for life this company is a hidden treasure. Thank you ARJ defense.

    Excellent fit and finish..zero play between receiver halfs and very nice details go into the machine work like raised sections align perfectly from upper to lower receiver..Extra reinforcement is done around fire control and breach, BCG to buffer housing is noticeably reinforced, the AR platform is highly improved with the use of a custom Billet from ARJ DEFENSE…You get well above the money level you spend ….
    I also bought the H1 rail to go with the M1 receivers for a perfect flow across the whole AR15 platform..Bought another set , will upgrade old builds using these affordable and high quality Receivers from ARJ DEFENSE..
