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.

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.

Poor quality. Misleading photos by Brandon, Verified Owner, 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.

Product Info for Aero Precision M4E1 Magpul MOE SL Lower Parts Kit w/No FCG

Install this reliable Aero Precision M4E1 Magpul MOE SL Lower Parts Kit w/No FCG to create a reliable rifle that meets your needs on the range, in the backcountry or anywhere else you need to protect yourself from wild life. Aero Precision designed these AR15 Lower Parts to work with their M4E1 AR LPK or any other AR-15 lower receiver since the parts are all built-in, and this kit is specifically lacking the fire control group - you won't be able to complete your rifle with anything other than a bolt catch and a fire control group. However, these kits don't come with a fire control group since it's included in the lower receiver. Put together your rifle using the components in this Aero Precision M4E1 Magpul MOE SL Lower Receiver Kit w/No FCG to create an advanced weapon platform that will allow you to take on whatever challenges come your way with an incredibly reliable rifle.image
