Great lpk

No fuss no frills just great parts from a reliable company.

You get what you pay for

by

It worked but I'll be looking for better in the future. The magazine latch holds a magazine but wouldn't lock onto the armorers block I have. I compared it to a bushmaster lower and the magazine catch is undersized in the CMMG compared to bushmaster. The takedown pins are not flat on the ends. Roll pin for trigger guard and the trigger guard are not included.

My go to lower build kit.

by

This has become my favorite lower build kit. I have tried an Aero kit on my recent Aero lowers and it isn't the same quality as the CMMG. The only thing that the Aero kit had over this one.. The little rear screw to hold the rear takedown spring and pin in place. If the CMMG had that feature, it would be absolutely perfect.

Close, but not right

by -

Everything fit and functioned as expected except the safety selector. Even after using proper lubrication and giving it time to break in the safety doesn't operate smoothly. It's rather annoying and I'll wind up changing it. Great price, especially when it's on sale but I would suggest picking a different kit.

OUTSTANDING

by

Great Quality, Extremely fast shipping and unparalleled customer service from PA. Thanks!

Excelent fit

by -

4th set. All the parts are within specs, good finish. The layout of the package is very nice in that you can verify all parts are present at the first glance. I will continue to buy this set.

Selector Switch Won't Fit

by -

I've done a few builds with the CMMG Lower Parts Kit. In the past these have been reliable, but lately the selector switches are way out of spec, and won't fit in the receivers. And in a couple of them the takedown detent springs are slightly too long.

BAD SELECTOR

by -

Parts kit is good except for a cheap finish on the magazine release button and the safety selector is out of spec by .10mm, scratched the finish on my lower.

Safety Selector Out of Spec

by -

I don’t know if I got a bad batch but my safety selector was way out of spec. I tried it in three different lowers including Noveske, Aero, and Anderson. Zero luck in any of them. Thank god I had an extra safety selector laying around. 4 out of 5 stars just because this is my first mishap with CMMG.

Quality isn't bad, but the selector is way off-spec.

by -

Other parts were fine, but the safety selector is way too large for the aero and Anderson lowers I have

Get at least one extra kit. Very good kit.

by -

Very nice kit. Everything is laid out nicely and labeled. Probably will order another one or two kits to have on hand. The fact they're on a card and not loose in a bag is very nice. All the pieces installed without issue too.
<br>
<br>The safety selector is also indexed on the right side so if your lower is marked on both side as to whether or not it's in safe, you can see that from glancing on the right side too.
<br>
<br>Our window to have AR parts and build them will close soon, best to have a few of these around.
<br>
<br>PA's shipping was incredible this order.

Pleasantly surprised

by -

I was pleasantly surprised with the quality of this kit. With the price point I didn’t have unreasonably high hopes, but after installation I found that all of the parts were seemingly perfectly in spec, and all the fit and finish looked perfectly fine. I was especially pleased with the bolt catch roll pin, of all things, which while not in any way loose, was also not nearly as big of a pain in the ass to install as most. My build is not finished yet so there are no rounds through this kit as of my writing this, but if you see no update to this review then I have nothing negative to report. I would buy again for sure.

Thumbs up

by -

Not much to say it's a parts kit and it works. What else do you need

Great Quality, will buy again

Great LPK

Should probably pass....

by

All of the parts fit well except for the safety selector. It seemed to be out of spec. Contacted CMMG to let them know the problem and they sent out 2 additional ones to see if they would fit. Both of the additional ones worked but quality control should have prevented the problem from the start.

Decent for the money

by

A decent kit of the money, but I had to go and buy another safety detent as the one in the kit was over-sized and did not fit.

Mostly good.

by

The parts come in packaging that doesn't allow them to miss parts. They are all labeled which helps when assembling your lower. My one gripe was that the safety selector was not in spec. It was bent in to where when flipped to fire it would catch the small lip on the lower receiver resulting in anodization coming off. Now I have a small silver spot right by the safety selector. I tried to bend it out but it broke. Ended up buying a safety selector from dpms which fit great.

CMMG Lower Receiver Parts Kit for AR-15

Good kit. Mine was missing the roll pin for the bolt catch though that is the only reason I am giving it four stars.

Quality parts and very good service.

Organized Quality LPK

by

All parts are separated and labeled in the blister pack. No parts are missing and if they were you would immediately know it. PA customer service was excellent as usual.

Just what I needed

by

This kit had everything I needed and nothing I didn't. I upgraded the trigger and grip from the start so I had no need for a trigger group or a2 grip. Price was just what I wanted.

Good quality parts kit

by

Had a grip and trigger already picked out, didn't need all the extras.Good quality kit, nothing bad to say, all good

Good price on a parts kit & I've found that CMMG kits are good quality. Besides, it's always good to have spares. As always PA is my go to supplier. Great service.
