Most Helpful Positive Review solid LPK for AR10 builders
I bought this in a rush for a custom AR10 build & was pleasantly surprised. Machining is top notch, particularly evident in the bolt catch & safety selector. I’m going to buy a few more for spare parts as needed, but I’ll be using this LPK on future builds.
Most Helpful Negative Review Parts shown are not correct
I bought this kit to assemble my Palmetto Sate Armory lower receiver. The pivot pin is not notched to sit flush in lower receiver. It does not come with roll pin for bolt catch release. It comes with screw instead and will not work in my PSA lower.

busted knuckles

by Sore thumbs, Verified Owner from TX, United States Written on March 29, 2025
every time I move the safety selector I'm reminded how horrible this kit is. The takedown pins require a hammer to remove and the safety selectors feels horrible each time you move it. I feel like I'm breaking it when I switch it. I had to disassemble my whole lower and starch my gun and bust my knuckle to remove my castle nut. Do not buy this badly made kit.
Pros:
  • None
Cons:
  • everything

not designed well

by Sore thumbs, Verified Owner from TX, United States Written on March 28, 2025
The color is not black so it stands out against the black lower. The take down pins require a hammer to push out which is horrible if you need to get in your gun without tools. There are sharp edges where things should be polished and smooth. For so few parts at almost 80 bucks its not worth it at all. The company didn't take their time to polish and take pride in their work. find something else.

Missing part, does not include what is shown in the pics

by Allen, Verified Owner from TX, United States Written on December 10, 2024
I got the package and its missing a part. I contacted OP and after a week they tell me the manufacturer says that part is not included with this item. It's in every picture, it's listed on the package, there is an empty space for it in the packaging. Why wouldn't it include that part? Makes no sense.

AR-10 Lower Parts Kit Bronze - Excellent Product

by DoubleEagle, Verified Owner from SC, United States Written on April 3, 2024
I purchased this product to match my Desert Raider AR-10 build from Aerp Precision. The bronze color looks great with the multi-color cerakote finish. The parts fit well and the machining is good on the parts. The kit does not have the roll pin for the bolt catch. It comes with a threaded post instead. If your lower’s bolt catch is threaded, it will be fine. If not, you will need to get a roll pin. My Aero lower included a threaded post for the bolt catch, so I didn’t need it anyway. I have used the Armaspec parts kits on two other builds, and I have been pleased with the results.
Pros:
  • good finish
  • good color selection
Cons:
  • No roll pin
Would recommend: Yes

AR-10 Builder Kit Awesome!!!

by Alec B, from FL, United States Written on October 2, 2023
I asked quite a few friends about a lower or parts kit and was having trouble finding one that was affordable and reliable. I called Armaspec and had all my answers within 5 minutes! Super easy to install and well made. Definitely will be back

I had an issue but it wasn't related to the product itself

by Burns, from CO, United States Written on May 4, 2023
The product is great. It arrived fast. The issue I had wasn't caused by the product itself, rather it was the PSA AR-10 lower. The bolt catch roll pin hole on the lower receiver wasn't made for the standard AR-10 pin. The specific PSA lower has to use a standard AR-15 bolt catch roll pin.
