BROWNELLS AR-15 LOWER PARTS KIT 5.56 NO FIRE CONTROL GRP/PISTOL GRIP

Well organized in color coded packets. All parts fit smoothly and quickly into an Aero lower.

Half the parts were rusty and the other half were so poorly machined that I didnt wsnt to use them. Ended up scrapping the trigger guard for really sharp edges, take down pins for being out of spec so they take alot of wiggling to work, and the trigger and hammer pins were completely rusty so I didnt use those either. I've used lots of Aero kits in the past, should have done the same with this build.

I don't understand all the 1 star reviews. I've installed four of these into RRA lowers and I've had no problems at all. Fit and finish is very good. Will be buying more soon

Good value if you plan to upgrade the fire control parts. Everything fits as should.

I had a grip and trigger so this was a perfect idea. Fast shipping. Great quality parts. All the parts listed were included, and fit perfectly. I will probably purchase another one of these kits seeing that triggers and grips are usually one of those things that you upgrade.

I dont know what everyone else's deal is, I had no issues what so ever and this was used in my first ever AR build. Love the color coded packets.

Product shipped was incomplete, missing magazine catch button and catch spring, as well as roll pin for trigger guard.



safety selector detent required hand fitting with file.



This is a good kind of kit to sell, but if you're going to sell it, have quality control go over it.

Bought this kit some time ago & finally tried to use on a PSA lower. The trigger guard is very glossy-black, a mis-match to the matte lower and other parts, so I took one from a spare PSA kit. The trigger guard roll pin was simply too large to be hammered in, so I took one from the PSA kit. The bolt catch spring was missing, so back to the PSA kit for that. The take down pin was larger toward the head, and would not go all the way in...so another part had to be cannibalized from the PSA kit. Pivot pin worked but the detent groove is rough and was actually rusty. Other parts were acceptable, but this kit is a waste of money in my opinion. Shame on Brownells for putting their name on a kit of this poor quality.

The pivot pin and takedown pin isn't long enough to fit my Aero lower.

I installed the mag release and bolt catch without incident, then proceeded to the pivot pin installation. Installation was no problem, but the pin would not release and slide open. I had to hammer like crazy to get it to finally release. I opened a second package to try a different pivot pin, spring and detent. Same thing happened with that package. I had to hammer like crazy and actually damaged the lower! I pulled a rifle out of the safe and pulled out the parts to compare. The detents in these LPKs are definitely a smaller circumference. They would go deep into the holes in the detent pin and would not properly release. Beware!

Poor quality, everything worked and fit, but roll pins were very tight, finish was inconsistent. Biggest thing was the pivot pin wasn't milled straight and when pushed home it took a chunk out of the corner of my lower, it's not going to hurt anything but to ding up a brand new rifle is a bummer.

Bought two of these kits, and had problems with both. Safety detents did not move freely in the lowers, and damaged the detent and safety selector. Had a take down pin that was not machined correctly, so the slot for the detent was not lined up correctly. And the Bolt catch roll pins are a very tight fit, one would not install all the way. Only Brownells product i would not recommend. Save yourself the trouble and get an Anderson or DPMS kit.

Exactly what I needed. Liked the color coded parts packets. Loved the steel (not brass) retainers for takedown and pivot pins, magnet retrieval when they fly away. I'll order again. My sixth AR build.

Used to complete an Aero lower. Everything fit and functioned but finish on mag release and trigger guard looked like cheap spray paint. Hammer and trigger pins were both undersized and a sloppy fit. I threw the trigger and hammer pins in the garbage, and have ordered Colt trigger guard and mag release. Really disappointed that Brownells put their name on this junk. Maybe saved me money in the long run as I will be much more skeptical of Brownells branded merchandise.

I have gotten quality parts from Brownells for years but this is an exception. The finish appears to be a shinny paint. The safety selector would not fit in the 3/8" hole. I had to sand selector to make it fit. After it was installed the detent was rough and the pointer was off. The detent Spring was bent. I take pride in my rifles and this kit is junk.

Both the roll pin for the bolt stop and the trigger guard were oversized to the point that I should have sent them back.

Finish on the roll pins is very thin so you will get shinny spots from driving the pins in, trigger guard is shinny/glossy, take down pins are poor quality, mag release okay, bolt catch okay, I used some of the parts to assemble a new lower on my day off, but some parts were very low quality and I regretted buying the kit.

Trigger guard shinny glossy not the proper matte finish.

Detents for take down pins over sized. Take down pins not so good . Nice mage Release. Nice safety nice bolt catch.

I decided to do a featureless build with a Thordsen stock (for California compliance) and this kit was perfect for what I was doing. The kit was well organized and it all went together as planned.
