LOWER PARTS KIT NO FCG/ PISTOL GRIP/ TRIGGERGUARD FOR AR-15 Reviews & Ratings

Most mil-spec parts kits come with everything needed to finish a standard, mil-spec lower receiver, but let's be honest. How many of those parts do you actually use? Most AR builders are putting in their own trigger and adding a pistol grip from a furniture set of their choice, so why pay extra for what you won't use? This Aero Precision AR-15 Lower Parts Kit includes everything needed to finish a lower receiver except for the fire-control group, pistol grip or trigger guard.

Takedown/pivot Spring
Takedown/pivot detent

Good Value for what it is

This is a basic kit at a basic price works just fine Ive been using these products for years

Functional standard parts set

Great for what it is - a lower set for those looking to select their own trigger and grip. Parts are all functional, albeit standard grade. Takedown and pivot feel a bit gritty and the finish on bolt catch, safety, and mag release are nothing special. If you need parts that work and are OK with phosphate finish - this is your set.

Good value

All pieces fit with very little fitting required. There was a little burr on one piece, but it was easily removed. Slight color/finish variations between some parts is normal with any lower parts kit. It that bothers you, get some paint. Id buy again.

Perfect kit for my use

I needed a kit with just the basics. I customize many of the parts so I don't need all the extras many kits include. This one has just the right pieces for the basic build. Parts were good quality and everything went together easily.

GREAT CHOICE

I have used this Lpg on 7 or 8 builds now... the springs are great quality and since I install ambi safeties, bolt catches and mag releases by Battle Arms Development with Bravo Co pistol grips with LaRue or Giselle FCGs I don't want a full LPG. This kit is almost perfect. I keep a collection of small parts anyway so I have backups on hand for everything AR related

Great Product

Very High Quality, and was better than expected.

As advertised

Installed without any problems. Components appear well-made and function as they should.

Good quality - only the parts I need

I installed this on an Anderson lower and it worked well. It only includes what I would use anyway, so it's a great way for me to build a lower. I used a Larue MBT, Magpul Trigger Guard, VISM Grip, and Adaptive Tactical stock to complete the build. This was a low cost, medium quality build for a .450 bushmaster upper for deer hunting.
