    Love it. I have 3 kits from Durkin now. I am a price shopper all day but these kits are fantastic. I couldn’t believe the quality for the price I was amazed. Smooth assembly and nice feel when done.

  3. Eviltwin

    Mine came with a Quad-Rail. It also included a Lightweight BCG, which i was not expecting.
    Definately worth the Price!

  4. Michael

    I was pleasantly suprised. Awesome quality for the price. Tested perfect. I added an arm brace and red dot and its ready to go.

  5. W. Browning

    It turned out nice. Needed a good reliable truck gun and this is it. No issues.

  6. Hayden Lee

    Looks great and shoots great. I completed my kit with a sba4 brace also from Durkin. My only problem was it shipped without a forward assist. But customer service set one out the same day I told them it was missing. I’m already looking at another upper from Durkin.

  7. Anthony McCardell

    Nice kit, dust cover and forward assist pre installed and dimpled barrel is a nice bonus, quad rail works for me too.

    Where do I begin. I’m so excited about my purchase this is my first AR-15 I was literally a handgun guy before this pandemic happened so I figured I should definitely get into rifles. After searching around I decided to build one for my first one. And after going to several websites I decided to buy from dunkin’ tactical. Although it took a month I am very happy with my purchase. The gun looks great it shoots well.

  13. Timothy Turba

    Crazy fast shipping in this day and age! Six days from order to in my hand with one day waiting at the Post Office because I wasn’t home. Barrel is excellent quality! Even has the dimple for the low profile gas block. Customer service is top notch. I forgot to put in a coupon code and they hooked me up with a discount on my next order. Please note you can get a coupon discount AND a military discount with the Verify ID. I asked for an M-lock rail in the order notes and got it. I can’t wait to put it together!

    I recently purchased this build for a dedicated truck gun.. Everything went together flawlessly… for the most part.. I had issues with a faulty gasblock.. I would give 4 stars because it wasnt 100% flawless BUT I contacted their customer service and they got me taken care of and the issue resolved within like 24 hours. Their Customer Service is aammmaazzziinnggg! If I could give more than 5 stars I would. Still have this rig as my truck gun today and don’t have a worry in the world as to whether it will perform is need be. I’m a creature of habit and follow what I personally experience.. and durkin tactical will have my business for life.

    Went together well. First build works good. Want to do another, maybe another pistol kit.

  16. clarkqua16

    Came quickly and i love it was a little confused by the barrel nut at first but figured it out all around love it though

  17. James Frazier

    Great kit!! Everything as expected. Will get another.

  18. Edson Franca

    The best value and one of the best customer service in the industry. They will stand behind what they sell you. I have bought from Durkin before and will keep on buying from them. Just because they are selling “value” kits doesn’t mean they are selling you junk, I’m 100% satisfied with their kits. Great job Durkin.

  19. rondogrape3

    Before I purchase I’m wondering what is missing from the kit that I will need

  20. Vinco

    I bought 3 kits from Durkin – two Black Friday 10.5″ pistols and a Black Friday 16″ carbine. I got quad rails with all 3 kits. The quad rails must be airsoft parts or something, because none of the 3 barrel nuts fit my Weaver (not cheap generic) armorer’s wrench. I managed to find CMMG barrel nuts which fit both my wrench and the quad rail correctly, for $20 each. The threaded lock ring is also too long to actually fit behind the rail without preventing the upper from being placed on a lower. Furthermore, 2 of the three upper receivers did not fit on either Anderson or PSA lowers. I was able to fix this by filing the rear takedown pin hole in each upper receiver, but if I was a novice at building, then I might not have figured out how to fix it.

  21. Robert Boley

    Good value and went together well.Works well with a good magazine.They shipped it in around 5 days.You cant go wrong with Durkin.Highly recomended

  22. carrej18

    Good value for the price. Went together easily and works great. Put 200+ through it right out of the gate worked perfectly.

  23. carrej18

    First build from Durkin. Overall good value for the price as it went together easily and works great. Put 200+ through it right out of the gate worked perfectly.

    WARNING If you don’t enjoy building/assembling your own NATO .223 from a quality kit by Durkin at a great price, then it’s your loss. My kit arrived in 5 days time and was fully assembled in 2hrs and 12 mins- i only mention this because it was as easy as the snap and fit beginers revell modelcar kits to assemble, and only needed a minor alingment tweak for the gas tube. I used a billet aluminum 80% lower for added weight and better feel (i also used a polymer 80% for mock up but with the 10.5 bbl the Al had better balance). No knock on polymer lowers, i have one on my 16″ .300 blk and i’ve put 375 rounds out and it feels right and light and stays FN tight. My only add ons for my Blk Fri were a Durkin drop in trigger- added a mnth later and under 75$, works great and a bargain for quality, and a red dot sight. IMPORTANT: Wear hearing protection! Cuz it is one LOUD MuddaFugga. The big fireball’s pretty cool too. Be Safe but Have Fun
