Most Helpful Positive Review Aero Precision M4E1 Magpul MOE SL Lower Parts Kit
Had everything I needed and parts fit great. I liked it so much that I ordered a 2nd one with a slightly different Magpul handle. Shipping was timely. Cost was competitive with other vendors. I'd order again.

Aero Parts for an Aero Build

by Rudy, Verified Owner from TX, United States Written on July 11, 2025
Aero had a sale on stripped lowers, and I had been wanting one for years so I ended up purchasing it. Wanted to put genuine Aero parts into an Aero lower so I ended up purchasing this. You will still need your buffer kit and fire control group but otherwise it is complete. Had to sand down the buffer retainer as it was causing issues with my buffer tube but otherwise everything else installed w/o issue. The grip feels a little narrow to me compared to other grips I have so depending on your hands it may not be noticeable. If I need another aero parts kit for another aero lower, I know where to purchase it again.
Pros:
  • being bob the builder
  • threaded bolt catch
  • threaded takedown pin
Cons:
  • does not build itself
  • small pieces can get lost if you are unlucky
Best Used for:
  • assembling an AR15(ar10 not compatible)
Would recommend: Yes

Poor quality. Misleading photos

by Brandon, Verified Owner from PA, United States Written on April 23, 2022
Takedown pins are rough and difficult to manipulate. Parts feel gritty and unfinished. Image clearly shows trigger guard but one is not provided in kit. PSA is better quality and at a great price point.
Would recommend: No

little deceiving

by tim, Verified Owner from TX, United States Written on March 10, 2022
Parts kit was on par for quality. Only issue is picture sows a trigger guard but it isn’t included. That is the main reason I bought this kit was it appeared to come with trigger guard. Other than that it’s a satisfactory kit.

M4E1 Aero Precision LPK perfect fit

by KenC, Verified Owner from NV, United States Written on December 20, 2021
Perfect fit with my Aero Precision build. I love that it comes with the Magpul trigger guard, even though I don’t need since the M4E1 lower receiver has a built in trigger guard. I usually save it for when I actually need it for my other build. All the components parts kit fits perfectly well with my build. This is my go to LPK specially when I’m using all Aero Precision parts upper or lower receiver. Highly recommended two thumbs up!
Pros:
  • Perfect fit
Cons:
  • Discoloration on some metal
Best Used for:
  • AR 15 build part or replacement part
Would recommend: Yes

Magpul grip and parts kit.

by Pots, from NY, United States Written on March 3, 2020
Aero precision parts kit did not seem like anything special but that magpul SL grip I like very much because it was extra thin. I will be getting more grips like this one. It's very light weight and strong.
