Most Helpful Positive Review Armaspec Lower build kit.
I have used this kid on 4 separate AR platforms and I refuse to go with anything else ever since I started using this lower kit. I have over 1000 rounds out of one AR and have experienced zero problems. Safety selector you can choose 90 or 45 degree throw. The trigger hammer pins are a better/tigh...

Most Helpful Negative Review Major fitment issues
For reference, my lower is a Aero Precision billet lower (NOT BLEM). Issues: Trigger pins have .5mm of play/slop. Safety Selector has 1mm of play/slop. Front takedown springs is crazy stiff (will probably break-in with time). I am extremely unhappy that these tolerances are so far off. I mean, ...

Wrong part packaged.

by MikeMike, Verified Owner from SC, United States Written on May 21, 2025
The retainer and spring that stop the buffer spring are way too big.
I had to take parts off of another rifle. During close inspection i think they might work in an AR 10. So now i have a spare. For someone just starting a build tho...

Very Satisfied with the whole kit!

by CatManDoo, Verified Owner from MI, United States Written on March 22, 2025
Before making the purchase, I researched the kit details from the Armaspec website to get more information.

I purchased the kit, mainly for the Stainless Steel components, like the anti-walk pins, detent pins and springs.
Weight was not a concern,
so being Superlight is not the reason I purchased it.
For now, I utilized the whole kit except the Aluminum Take Down Pins. I am using a pair of Rainier Arms Black Stainless Steel Take Down Pins.
(I did try the Aluminum Pins, just to see, and they both fit and worked very well, without an issue)

The lower is an Aero Precision M4E1 threaded, black anodized.
I mentioned the color, because I don't know how thick the "Cerakote" colored coating is and if it reduces the hole diameters.

Maybe I am just lucky, I don't know, but
I did not find one problem with anything.
Bolt catch, Magazine Release, 45/90 Safety, all fit nicely, and work without an issues.

After discount it cost me $55.
Armaspec sells the kit for $79
Received in less than a week via FREE shipping, in a well padded box.
So I am very pleased with the purchase.

Decent but an issue

by mistakes happen, Verified Owner from TX, United States Written on April 24, 2023
I got this as I needed a lower parts kit and anti walk pins. The issue I ran into is the spring for the safety selector does not put much pressure on the detent. I feel like a strong breeze can move it as I can barely touch it and it will move. The is the first and only lower I have put together and had this issue so far and this was the first time trying this kit as I usually get just an aero precision lower kit for the other builds that got lost in boating accidents
Pros:
  • lost of parts for decent price
Cons:
  • very weak safety spring in my kit
Would recommend: No

Takedown Pins are too hard to use and safety too long

by Somebody, Verified Owner from WA, United States Written on February 3, 2023
It looks cool and I do like how far the mag release button sticks out, BUT the takedown pins are very hard to push. The front takedown pin I have to tap with a hammer to get it to pull out. The rear one I can do with my thumb, but it takes some force that I have never had with other takedown pins. The detent holes are way too deep compared to other takedown pins.

Additionally, I wish the safety selector switches were shorter and more slim. They are always in contact with my thumb and trigger finger.
Pros:
  • looks sweet
Cons:
  • Hard to operate
Would recommend: No
