Most Helpful Positive Review Aero Precision M5
Fitment was prefect. takedown pins/safety selector/bolt release function properly.
Most Helpful Negative Review Very Disappointed - Front Pivot Pin
I built an AR15 with a Strike Industries parts kit and like it quite a lot, so I felt good about using a Strike Industries LPK for an AR10 build. The AR10 build went together well until I tried to attach the upper and lower. The distance between the detent and the end of the front pivot pin is too...

Great parts to finish your AERO PRECISION

by Matt, Verified Owner from TX, United States Written on June 14, 2026
I have purchased Aero Presicion lower and upper for more than a year. The rest of the parts are always out of stock everywhere. Now my AR10 is finished mostly because of this kit. Highly recommend if you are looking for building kit for your Aero Presicion lower.

Good for my needs

by Themuphinman, from PA, United States Written on February 22, 2026
Waiting forever for the aero m5 kit, so bought this in interim so it's not all in parts. Takedown, pivot, all works well, still pending a trigger. Clicks are audible and smooth, if you want to use the aero m5's takedown pin detent spring screw (the 4-40 one) then you will have to cut the detent spring in the kit to about 3-6 coils over the surface when resting on the detent, and you're good to go. Cant wait for that trigger. Set looks much better installed than the aero kit am waiting for, will see..
Pros:
  • Easy to install
  • In stock
  • great description online to identify parts
  • quality looks good
  • ambidextrous, good sounding clicks
  • cheaper than others, great quality
Cons:
  • no trigger or handle
  • not free? :(
Best Used for:
  • aero m5 308
  • ar-10, not sure of ur lower though
Would recommend: Yes

Safety Goes to "Safe" Roughly After Firing (Shouldn't Do That) + Rear Pin Oversized

by wildcatgoal, Verified Owner from GA, United States Written on February 7, 2026
I tried with two different triggers and still the included safety operates normally when the gun is cocked and locked but ALSO operates after firing. The safety should not operate (go to safe) when the gun isn't cocked and this indicates something in the design is out of tolerance. I have a hard time trusting it and will quickly be changing it for something more trustworthy. I'm not so much annoyed it will go into SAFE when it's not cocked but it causes the BCG to bind and the trigger to, hard to explain, feel like you're griding over the safety somehow. I can't help but think it will eventually wear and/or break. Additionally, the rear pin in my kit was oversized in diameter vs. milspec and weirdly long (sticking out more than the front pin on the left side of the gun. The front one was slightly smaller and fit perfectly (correct milspec nearly exactly). These tolerances are not to be messed with, it is the prime standard, and the lower these parts are going into is a high end billet unit. Everything else that came in this kit is fine... but those things are always fine in any LPK. This was my first Strike product and it will be my last.
Pros:
  • Bolt Release Design
  • Mag Release Smooth
Cons:
  • Safety Doesn't Work Properly
  • Takedown Pins Wrong Size
Best Used for:
  • Out of Spec Lowers
Would recommend: No

Read the description!

by Juan23, Verified Owner from PA, United States Written on January 26, 2026
This is a quality lpk, everything fit well, and it functions as intended. Also, it looks good. I've seen a handful of negative reviews where people are complaining, "It doesn't come with everything" or "it's missing parts"...It's NOT SUPPOSED TO!
This is not a complete lpk. If you read the description or look closely at the picture, you'll see everything that comes in this parts kit.

This was my first lower I built so having at least a list of what part is what would have been nice. Other than that it all went together just fine
