Customer Reviews for FMK Firearms AR-15 Stripped Black 223 Remington/5.56 NATO Lower Receiver

I have built 2 budget rifles off of these lowers and they have worked exceptionally well. Main use is plinking with a 16" 5.56 upper.

Well worth the money great polymer lower. Will be buying more! FMK done a good job with this for a budget build it’s perfect.

Great quality polymer lower! US company out of CA owned by a former Marine. FMK = "For my Kountry" No issues. Solid lower. Many colors. I have a few.

Nice product.Nice price.will but again.

I have no complaints! A reasonably price lower that hasn’t done me any wrong in the years I’ve had it!

Bought this for a budget build. Very good quality for low price.

Looks good and works great, like the the look of it

Extremely lightweight and also a little on the flimsy side. It would not drop any or accept any 30 rd hex mags without slapping them into the gun. I put a PSA build kit on this lower and ran around 500 rounds of .223 through it. it didn't get hot and zero signs of wear.

Very good lower for the price. The proprietary composite polymer seems extremely sturdy. I do not doubt the strength of the product. Lower parts kit went in smooth and tight as any other lower.

Fast shipping from buds! The lower receiver is very light weight and work great for building a light weight ar15 pistol. Everything assembled easily.

Light weight well cut will buy again

Easy purchase and shipping as stated. Will buy from Buds again.

As good as any other stripped receiver I have purchased at this price point. Compares to the Anderson lowers Classic sells and is about the same price. You won't be disappointed using this lower for your next build.

I bought this lower with high hopes that it would be a good product for my AR pistol build. Initially I had thought this lower would be sturdy and lightweight, perfect for a pistol build. But upon attaching the buffer tube, I noticed that the rear takedown pin was almost impossible to push to the side (in order to attach the upper receiver). I also noticed that the detent that holds the takedown pin in place was bulging outwards and pushing on the takedown pin so hard it couldn't hardly move. It seems likely that there was too much room in the space where the spring and detent go and the detent went in slightly sideways. The lower also flexed a great deal to the side when I was screwing down the castle nut. The whole thing is rather flimsy. Buy at your own risk

This is a polymer receiver, which I somehow missed when ordering. Oh well, built it up anyways, everything fit as it should. Interesting concept and I like it. Clean no frills lower with a nice finish. There is some flex near buffer tube area, not much, but when compared with aluminum one - where there is no flex, hard to ignore it. So far so good, hope it holds up.

Haven't used it yet ? It'll be OK though

Love it really lightweight gets the job done no complaints

Once again Buds has delivered outstanding customer service and an excellent product. The FMK lower receiver needed no modifications to make everything fit. The build turned out nice.

This was my first polymer lower build. Excellent craftsmanship. Easier to install lpk than aluminum. I will purchase another. Buds has quick shipping as well.

Worked great for my build

Bought this lower a couple of years ago and pinned on a 223/5.56 upper.Shot about 500-600 rounds,no problem.Pinned on a 9mm upper,fired 3 rounds,the lower broke at the rear pin.I don't know what to say,it ran fine with a rifle round but it couldn't handle a pistol round?Don't think I can ever trust a polymer lower ever again.Buyer beware.Even though it has a lifetime warranty,I'm sure it's gonna be a hassle to get it replaced.

Excellent service and fast shipping from Bud's as usual. The polymer receiver was in excellent condition.

Great experience with Bud's once again. This is my second polymer lower and the first is still performing well two years later. Great lightweight right priced lower to start your build.

Surprisingly light lower. All mil-spec parts went in without a hitch. The upper seems to fit with less play than I normally see with an alloy lower. Builds into a very solid rifle. As always, an easy transaction and a good price. This is at least my 8th firearm purchase from Bud's and I remain a loyal customer.

I HAVE PUT ABOUT 1000 ROUNDS THROUGH THIS FMK. I WOULD BUY THIS LOWER AGAIN IN A HEARTBEAT. USED A M-4 KIT AND EVER THINK WENT TOGETHER LIKE BUTTER. YOU WILL NOT GO WRONG WITH THIS LOWER!
