We love these!! Use them to put together various rimfire calibers for folks in this part of the country to protect their flicks from varmints. Trigger is much better than milspec, makes a great, easy to tote lightweight solution.

I had my doubts about plastic lowers for the AR15 rifle, but it works as flawlessly as an all-aluminum alloy MILSPEC lower. Everything is tight in fit and finish with the carbon fiber composite. The best magazines to do mag flips are the Lancer L5AWM. Everything is solid and it works 100%. I am very impressed with the plastic trigger and the plastic safety switch (the magazine release is metal to metal for durability and positive lock up). I purchased two lowers at the same time for a double-duty torture test for the next five years. We shall see!

This is my second one, the first was bought some years back, (8 - 12 ?), I found that one to increase accuracy of loads with each upper I tried it with. This one is now under a short stroke piston upper, ( they can use a little weigh relief), I just shot it to check function , it ran smooth and turned in a .67" group with a Know Good Load for that upper, and @ 1/2 pound lighter... I like them and would put it on the line with one....

Okay, so I knew this was a base polymer lower. Lightweight and strong like the reviews and a friend of mine said. But I didn't know EVERYTHING was polymer, the safety switch, the hammer, other internals. I did NOT feel comfortable with a plastic hammer or retention pins; felt iffy about a plastic trigger. So I switched out everything for steel except for the safety selector. Other than that this thing does save some weight compared to an aluminum lower. Not that much though. Oh and the main reason it loses a star is that no magazines I have will drop freely after pressing the mag release. Even Pmags when fully loaded won't drop free. So I would never trust this thing to be a "SHTF" lower, it will simply be a lightweight hog hunting/range toy build when I get an upper for it.

Love the price Have Numerous older model LW-4 , Great overall Value.

I originally purchased this item in January of 2013. I mated it to a PSA complete M4-style carbine upper. All pins were replaced with aluminum, the fire selector is steel and the trigger/hammer/spring setup is the PSA enhanced trigger group. Everything else remained the same. I have had zero issues from this lower and my friends are jealous of the lightweight rifle I have as compared to theirs. My LW-15 lower has not shown any signs of wear. I regularly shoot both M855 as well as civilian .223 through my rifle. If I had to do it all over again, I would have bought 5 of these lowers at the same time. I was not paid to leave this review and am a real customer residing in Louisiana.

Between my son and me we have purchased about 18 of your polymer AR lowers. Started buying them for personal use right after the initial testing was finished. We have subjected them to all manner of abuse. Actually we gave a new meaning to abuse. You used to have an email from me with pictures in your store on the top of the back rear right display case. The email and pictures were of and about my polymer AR that I ran over with my Bush-hog, cut the upper apart with a saws all, replaced the takedown pins and the upper, shot a half inch group with it the next day. It is still in my rack. I run several 30s, 223s and a 358 MGP in the lowers. No need for wedges, special mags, pins or anything else special. They simply are great lowers, period.

Bought my first back in 2009, don't remember if it was called LW-15 or not? I have put a Stagg Arms 5.56 and Olympic Arms 7.62x39; both hit what I aim-and I only aim at what I want to destroy. Tremendously light, much so it makes the weapon very front heavy!!! There is no real weight at the rear end of the rifle, so don't consider using that end as a headsplitter. These should last a life which is variable. I was diagnosed sever anxiety and insomonia disorders. Not enough. 2 months ago with 3 bulging or burst vertebra,stenosis (sever scarring of the spine) and degenerative spinal disease. Not enough. Last week diagnosed with a massive malignant tumor in and around my thyroid glands,lymph nodes, etc. So lasting a life time for 57 year old is an interesting reflection and introspective pondering. I may do a last firearm build especially for my Dr. Nephew and his Sister Dr. Niece both can choose from may firearms collection. Many have asked me how many firearms I have; I'd sooner tell them my unemployed LWOP than answer their question(NOYDB). You NEVER HAVE ENOUGH of WORKING FIREARMS AND good quality will protected AMMO. I spent the first 20 years in marketing and pr asking people to donate blood to save others in hospital through the US. The 2nd almost 20 working for the Federal Gov't, as I was to old to join the military when 9Sept2000 brought the beginning of the war to our HOMELAND. Ten's of thousands have died and 40,000+ have been maimed protecting all of us. I finely got hired by the TSA (worst Federal Agency ever to my knowledge-all of them mostly are-biggest violator of EEOC Law is........... .....?????come on America you can guess it=USA Fed. Gov't). Then to the USAF as a gym trainer, sport field prep,etc. as a temporary full time emergency hire-the airmen wore being deployed.USAF Fed. park ranger/warden,US Army Fed guard/ police chemical weapens guard, US Army Civilian Police officer and armorer, V.A. Civilian Police Officer(shameful how they and the general public treat our Veteran), and then back to the USAF as a Physical fitness tester(I'd been hired with the assurance of being in the first bunch of the "guaranteed first hires" to start of the Civilian Police/Security Forces-let me sell you winning lottery ticket.I've Sworn my personal Oath to the Constitution of the US. For you that are truly privileged to be "allowed" to own a firearm and be raised up with one. Our ONE Nation Under God is tearing it's self apart AGAIN. After 9-11all the Liberal top to bottom begged, fake prayed for God to help us, all the while continuing to plot for all individual Citizens to be unable to legally possess, much less own a firearm equalized. An Armed Society, is a Respectful, well protected one. We've let the liberal insult our intelligence by telling us to let the Police protect us ONLY---when seconds count, the Police are 15 minutes away or more-they do Police reports about what happened,etc., poor victim.I'll always be and act like a Police Officer, I'm no better or worse than any else I'm paid to if necessary forfeit my life to protect-our current batch of P.O. for th last 10 years, are shooting civilians, unarmed criminals, armed and supplied with Military weapons and Vehicle as if they are at war with the civilian populace. I'll die with my firearms and leave them to family members that value Freedom enough to arm themselves are are willing to defend their family. May the Lord continue to Bless Our America-please.

I have owned this lower for about 3 years now. this thing is awesome! I have put around 5000 rounds in to it and its still kicking. The blow back hammer is getting a detente in it. I would like to say good job NFA. Also the Customer support was awesome. I had a problem with my rifle when i 1st built it. It was the upper. I did kill my Magazine Catch after or around 4000 rounds Plus Drills. Most people well be lucky to hit 2000 rounds in the lifetime of there lower I replaced it with Metal Magazine Catch. it was like 10$.

I wanted to wait a bit before writing a review. You just can't give honest feedback with something so new. So, now that I've had this thing for a couple of years, I feel I can give an honest, as well as informed, opinion on the product. I FREAKING LOVE THIS THING! I set about building a bargain rifle. Which I did. Since then I've changed out a lot of the components and turned it into a pretty decent lightweight patrol carbine, But first... I actually put the rifle into a stressed position for six months to see how resilient this polymer lower really is. I changed the temperature up and down rapidly, and the humidity as well. Just being thorough. To this day it still functions flawlessly! I love the polymer lower kit in this thing too. The trigger is sharp and crisp, with a short reset and it doesn't creep at all. Don't let the, "plastic," parts fool you. It may look like an airsoft or toy, it is not! It is a precision crafted machine. Is it perfect? No, of course not. I do have a few minor issues with it. The hammer that's included will work with milspec BCGs, but some others have a tolerance issue. Not a big deal, just a minor issue. I swapped the grip for something a little more ergonomic and had to drop an extra roll pin in there to make the safety engage. The pivot and take-down pins are so stiff that I need a punch to remove them. Again, not a huge issue, but it is an issue. None of these things would prevent me from buying another, or recommending one to a friend on a budget. All in all, this is the BEST VALUE on a lower that I have found anywhere in the market. And as soon as NFA starts making this thing in FDE, I'm buying another!

I was on the fence for a long time in regards to purchasing the NFA Polymer lower sue to other sites claiming lack of strength/durability. I went in and purchased a 5 pack and split with up a buddy. I can say in the last 2.5 years of heavy shooting on all 5 lowers, we have not had a single issue. That says a lot about the quality and consistency of manufacturing. We are running a range of uppers from 10" barrel pistol setup to 24" long range upper. We are not easy on these things by any means. The weight reduction is a huge plus. Running DPMS, Rock River Arms and other brand uppers, all perfect fitment. I will be purchasing more when back in stock! Thank you NFA for an awesome product. ~ Ryan

Thanks for the feedback Kevin, we're glad you're happy with it!
