  1. Rudy Flores

    Great product and all parts very durable. FDE Cerakote is a good durable finish and scratch resistant. Awesome price and highly recommended!

    Best build kits out…I refer so many people to this site its crazy. Why over pay for an AR when ALL YOU NEED IS DURKIN

    I received my kit WAY sooner than expected , awesome Job DT.
    I did not get the quad rail I wanted , not a good start
    I did however get a billet upper and a ambi charging handle !
    Now the ambi charging handle is cool and saves me from having to upgrade ,
    The billet upper is ….well I can do without a forward assist because I was taught to NEVER use one but I am curious why the machine work wasn’t completed as evidenced by the razor sharp edges and the ejection port not being finished enough to allow the super cheap Chinese dust door to engage and stay closed . That being said , I FREAKING LOVE IT , I mean if I could fix the issues without messing up the cerakote , I’d wear it around my neck like jewelry. I’ll eventually fix it .
    The rest of the parts are pretty standard , the finish on the buffer tube is a bit shiney and the buffer rattles internally ???
    All in all , a good solid pistol kit that I will enjoy for years ,
    Would I recommend this kit to others : As long as you don’t have your heart set on getting specifically what you want , and you don’t mind fixing the little things , ABSOLUTELY , I will probably buy from them again and soon

    For the money this is one of the best kits on the market. I’ve built several AR’s over the years, some expensive and some were budget builds. This one is obviously a budget build gun but for the free floating barrel it’s a steal at this price. All the other parts are pretty standard but for a little extra money you can swap out the trigger kit and change the stock (in this case, the brace) and have a very nice little AR pistol. I would certainly recommend to anyone looking for a gun to beat on and use as intended. I did have a issue with the bcg not closing as it should but 2 minutes using a fine grit sandpaper fixed the issue. I definitely recommend testing moving parts as you assemble. That way you can do the little tweaks as you go. I’ll be buying another one (once they are available again) for my son. Thanks Durkin for the good biz and quality parts!
