Ok, so there's a lot of haters out there when it comes to poly lowers and there is at least some history of the Plum Crazy lowers failing... but has anyone actually killed a New Frontier yet?
I bought one and have every intention of doing my best to beat the absolute $%!# out of it until it gives up the ghost. I intend to post my findings in this thread and I invite anyone who has a New frontier that has failed to please post photos and a description of what happened. I feel that the community has something to gain here but please keep it to New Frontier only. We already know the Plum Crazy has "issues".
I have no horse in this race other than my own curiosity and a desire to really beat the hell out of something... I don't work for or sell New Frontier parts or any other firearm parts for that matter. I intend to post the honest truth about these from my own experience as there seems to be a lot of talk and not too many real life accounts about these poly lowers out there on the interwebs.
Let's try to keep it to factual experience please. I know many of us don't like new and different and that many have the opinion that poly sucks no matter what. There's loads of those threads out there already, please no thread crapping because you have an opinion that has no factual basis. Myself, I'm on the fence. I don't know if they suck, are indestructible or make me better looking. I wish to find out and share with all of you and hope that others will share as well.
Thank you and please be safe.

I haven't even tried mine on for size yet.......but after I get my upper pretty soon I'll find out and report back in the new year. Mines a low number too so I don't expect anything to happen but who know. Besides that doesn't Frontier warranty their lowers for normal usgae????

You should put a question mark in your thread title so as not to inadvertantly cast dispersions toward the good guys at Frontier, or what appears to be a pretty decently solution for an ultralight AR solution. Just sayn.

Change out the hammer to a regular hammer. Not a plastic one. That being said mine works fine "as is" with a taccom3g .22lr upper

To be honest , I bought the lower because I wanted to prove to myself that you get what you pay for , and at 99$ I couldn't say no . Before I purchased it I had said to myself " we'll ill change the internals to metal parts " put a decent trigger on it . Now that Iv played with it on my .223 upper my 7.62x39 upper and finally the Beowulf , I'm very impressed !!!! This thing brings the weight of my rifles down to something a lot more manageable ! And the trigger !!! I have to say its better then any mil spec out there ! Almost comparable to my Nicle boron alg trig . But nothin like my timney of course ... All and all I think I got a lot more then I paid for :)

Chewbacca, how much of the original New Frontier Lower LW15 have you 'changed' out
that doesnt look like the stock or pistol grip, what else was actually changed?

Is it a misfire issue? this might help!
You need to make the hammer narrower as 22LR bolts are pretty narrow causing the hammer to rub on the sides resulting into misfires. this is how the hammer should look like:

I've had a New Frontier Armory LW-15 lower for awhile now. Started off with a SlideFire Solutions bumpfire stock and have ran nearly 1,700 rounds through it. Including about 250 earlier today. Got some video of a mag dump from it as well. I loaned it out to some friends to abuse too. I've heard of some issues with the internals so I wanted to push them a bit. So far, so good and all with the stock lower internals.

Is this for everyone? No. But their certainly is a market for it.

I'm currently writing a review of it and have 3 complete lowers to give away. I'm going to try to get the review finished up and posted tomorrow.

Just a quick update.
So I've beat the absolute dog snot out of it and so far, no issues.
I did have a little trouble with my polymer upper(Hesse, polymer upper with my parts), after blowing through about 200 shots rapid fire... Very,very rapid. Gas block was so hot it melted the piece of carpet I set it down on... I noticed my back up sites looked a little weird, barrel nut was loose. Not very loose, just a tad. Tightened it back up and retimed it for the next hole, 27ish ft,lbs. Not a single problem sense and I have NOT been nice to it.

This is good to know; had one for a while but yet to slap on an upper and taker her out; I will try it out soon. I think I will pair it with a PSA or Bravo upper if it works out.

Hey Chewbaca, which take down pins did you use? I don't like the feel of the plastic either and tried to replace them with pins from a Noveske and a new DMPS lower parts kit. Neither could fit even after a dropped a lil oil on them. I didn't want to force them in hence why I'm on the forum looking for examples from other owners.

Thanks!

^^^ Same here.

Got the upgrade parts from Joe at Parallax Tac (where we bought the NFA) but haven't installed it, want to see if/when anything fails. That said, ours is a "spare" and still kind of feel it's a budget back-up to our usual ARs (running with JD lowers/DD lpk).

Was also going to put the JP yellow springs in it, but decided to just run it stock and see how it holds up.

Have a good weekend. :)

I just had some issues with mine. I took it out first time and fired about 100 rounds, worked well.

2nd time out, put about 100 rounds, sighting in iron sights and plinked around.

3rd time: Took it out to BLM on 11/10/12 and after first 10 rounds, switched to a 22LR conversion and the rear takedown pin broke. Gun was temporarily fixed, gun would then eject a round and not be ready to fire a new round. Not sure why, I would have to pull back on charging handle, and cycle new round (Ejecting a live round) gun was then in cycle to fire (Not sure of terms I was using for cycling, ready to fire, etc).

I was then taking rifle apart to clean and noticed the front take down pin was broken in half.

Question: Could a not properly fitted temporary fix cause the cycling problem? Not sure if cycling is the term as the rifle did eject a spent round and cycle a new round, the gun just wasnt ready to fire (Hammer?).

Or could a not noticed front take down pin cause a problem?

Im thinking with a temporary fix or a not noticed front pin would have possibly changed the alignment.

*This would happen at least once or twice in a 10 round mag.

*Did the same with the CMMG conversion.

Mine is running just fine. Just returned from a week long desert shooting trip and the NFA lower is exceeding my expectations. Absolutely no problems.

I'm picking one up from RifleGear on Sunday. I had an upper in the safe for awhile and figured for $109 it would give me a complete rifle. I'm anxious to see what they are like - first thing I was thinking about was changing the pins out, then the trigger - and I had to stop myself. Its a $109 lower, with a lifetime warranty and I'm putting it on an extra upper I had sitting in the safe, who cares if anything on it breaks??

11-12-2012, 8:34 PM
I have 5-600rds through mine and has never had a problem.

+1 on whoever said it'll make for a great lightweight build. It's what I plan on doing when I am willing and find a great deal on a lower to replace the current.

$110 for a COMPLETE lower is by far the best deal out there!

I've had mine for about 7 months and no issues. All I've changed out is the pistol gripand added a magpul ASAP. I have a CMMG 22lr upper and functions fine with the stock plastic hammer/trigger internals. I have fired about 1500 rounds through so far. For $99 plus tax and dros, you're not going to get a better deal on a decent complete lower.

Chewbaca
11-21-2012, 9:47 PM
So I had a problem with the Beowulf , after every few rounds it would drop the mag . I assume it's due to some sort of flex and or the mag catch being made of a flexible plastic . It did it multiple times , Iv since then swaped out the mag catch for a metal one . And the issue has seemed to be resolved .

Wow, hope it's just that!
I think I will swap to a mil spec lpk for reliability when I get mine.

Much like everyone, I have about 2k through mine and no issues. My only gripe is the poly mag catch. I am planning to replace it with metal as it flexes too much for it to work well with a Prince 50 convertible. Other than that, love it.

I think I will replace the entire LPK with a metal, mil spec one.

Not that i doubt the poly internals.

if your plan is to replace all the internals with metal ones anyway, why not just buy a regalar lower and LBK?

$110 + 50 for an LPK = 160

vs

$89 + 110 LBK = 199

My bad, misread your post.

Maybe that $40 savings as well as the reduced weight of a polymer lower is a selling point for some?

that's true

but i'd be willing to bet that most people are buying it for the "economy" factor.

so that was my suggestion, i'm not bad-mouthing the NFA lowers.

Just seems to me-lightweight builds notwithstanding-for just a little more, you get a forged lower that will last you quite a bit longer. Especially if you plan on replacing the internals with a standard LPK anyway.

Current PSA prices will get you a complete lower (if you find a local stripped lower for $89) for $206 vs. $131 for an NFA ($75 difference), and only a $25 difference if you decide to switch out your NFA's internals with a standard LPK

Funny....glocks are poly, and they last forever. But for some reason a poly AR lower wont.



People need to give it a rest with that crap. 95% of shooters here don't even put enough ammo through the gun per year to break the damn things in.

Many of the poly guns have a proven track record.

I know SCARS and such use polymer lowers, but they are also designed differently than an AR

Poly AR's have been out for quite a while now, and the older ones held up pretty damn well also.

And AR's still put very little stress on the lower. Really the weak point is slamming open the upper during dissasembly, but that is a weak point on alum lowers also ( albeit not as bad ).

and takedown pins, from what i've read.

Again, i'm not really knocking them a lot, i was just doing a cost-analysis on current prices.

It just seemed that the general consensus has been to replace all the plastic internals with traditional LPK parts, in which case to ME, it seemed more logical to just go with a standard type lower since buying another LPK negates a lot of the initial savings to begin with

Take down pins have been redesigned from what I have heard. As for replacing the the internals, that's just paranoia from the first gen ones carrying over, and this hatred for all things poly people seem to have.

Personally I won't be replacing mine, it has a damn good trigger pull. Much better then most the standard LPK's I've shot.
