    I’ve built 2 Renegade’s (.300 blackout and .223) and I’m happy with both. I’m actually considering buying another receiver and building one in .450 Bushmaster.

    Very nice Finish and fit up , easy to assemble , have 2 calibers 6.5 grendel and 7.62×39 .Makes a nice light hunting rifle ,
    would definitely buy the big brother .

    I purchased my second Renegade and have been happy with quality, fit / finish and function on both of them. As an earlier review suggested a bolt catch/release would be nice. I would like to suggest that a quick release adapter for the buffer tube would be a great idea. The Just Right Carbine offers one. Although, the adapter requires a proprietary buffer tube and the JR tube is com spec.

    Runs as expected…strange feeling when you shoot it and no recoil of the bolt… Fairly simple build, even with my lack of gunsmithing knowledge…used my SW MP15 for a donor…. would like to get another Renegade, this time, complete rifle.

    The good:

    Really nice machining nice smooth metal no signs of poor attention to detail really like my FDE finish its nice and smooth and covered the receiver well its darker than the pictured finish really happy. I installed an 18.5 Lilja barrel and am regularly shooting sub .5 groups.

    The bad:

    When the Cerakote was applied the inside of the pins holes and other tight spots weren’t plugged or protected from the finish I had to take small drill bits and an exacto knife to get into these areas and clean/scrape them out (by hand not power tools as I was worried about damaging the receiver) to make the trigger group mag release and catch pins fit and function smoothly. this build took me about 4 hours to complete I would guess the guys that get the black model won’t have this issue.

    The ugly:

    Oh my god, please please figure out some sort of bolt catch/release. Trying to fit a pmag that won’t allow the bolt to be closed on a full 10 rounds is a bear, also leaving the bolt open at the range to cool is impossible with out jamming something in. Want to have a quick clean and run a rod down the barrel? nope you have to pull that bolt and take the buffer tube off, its really inconvenient and the only thing I really hate.


    Over all I love this rifle my friends are always trying to get behind it and shoot it. highly recommend if you have ar parts lying about, you will be able to build a nice accurate compact rifle you can use to dominate dog town. Once you get past the bolt catch issue and used to cocking it every shot its a slick little rig.
