Ratings & Reviews
Great Lower Parts Kits
by Edward -
Bought 2 of these on sale. Fit my Anderson lower perfect. No issues. The trigger pull on these have been the smoothest of all the kits I’ve used, and I’ve used almost all of them. I will definitely be buying more of these.
First time install five 🌟 result .

This was my first time putting a lower together. This kit is easy to install everything worked accordingly. Im really impressed on how smooth the trigger pulls. I recommend it.
Just as described

Bolt catch broke
by Alejandro -
Dry fired and bolt catch broke.
Fair Kit with good FCG.
by John -
Mag catch was out of spec. Needed some fitting with a file. Safety detent was way out out of spec. Would not engage properly allowing selector to flop around. Tossed in trash, used the one from the Anderson Whoops! kit. Fire control group was actually really nice. Clean 6lbs -ish break. Springs all good. Take down/Pivot good. Used KNS antiwalk pins so can't comment on trigger hammer pins. Anderson Lower A2 Clone build.
Terrable but true. . Do Not Recomend.

I received the kit today and could not be more disappointed. There are parts missing and the parts that did come in the package will have to be cleaned and re-coated before I can even use them. I have built many lowers and I probably wont even keep this junk for spare parts.
Very poor quality and out of spec.

The first issue I came to was the disconnector. I messed with the trigger for quite a while trying to get the pin through. I checked and the hole in the disconnector is too small for the pin. Luckily, I had an old DPMS trigger group lying around from when I upgraded another rifle to a two stage trigger. After I got it together, I found that the magazine catch is out of spec and doesn't catch the magazine. It looks like I will have to take a file to the catch to make it work.

Worked as discribed. Finish is as expected but the trigger averages about 2.5 pounds.

All of the parts were in spec. Fit and function were good. The two noteworthy items are a very nice billet trigger guard and the trigger
<br>itself. Mine was around a 4lb break and its surprisingly clean. I found that i shot well with it. I have 2 lowers with the bcm pnt triggers and this one feels better and i dont mind saying it.
Finished my M16A1 project

This is a great lower parts kit for the price. Used it to complete my M16A1 build (the A2 style handle just went in my parts bin).
