Huldra arms 5.45x39

[mestes]

Well I figured I would post my build. So finally got my upper from Huldra arms 5.45 upper in. It is the same as it is made by adam arms but with a much lower price tag. The upper seems very well built. The lower is a new frontier armory LW complete lower. Currently installed is a Magpul MOE forend with 7 rail and a Rail Sling attachment from magpul. And sports a GG&G foregrip. It weighs in only 6.27 pounds for a Piston upper ar. Things to come are MBUS sights, CTR mill spec stock, troy battle sling, maybe the larue tactical risr and pod depending on the optic I go with. And I am going to try the window pmag mod to see if it will actually work. And maybe a light. Mostly just gong to try and stock up on as much ammo as I can right now. Here are some pictures.

Nice gun! How does it run? What mags does it use?

[jreifsch80]

Ooooo I have a new frontier lower that I should do the same thing with ;) nice build

From my experience with the LW15 and 5.45 milsurp ammo, you'll need to swap in the extra-power hammer spring to get reliable ignition out of the the LW15 polymer FCG.

I've had about 20 light strikes (fired on recock and second strike) out of about 1500 rounds of 5.45 I've put through my M&P15 5.45 upper on an LW15 lower with stock FCG.

I hope to get it out this weekend. It came with a stronger wolf spring to replace the stock one. Great price and cheap ammo! Will post as it gets more parts and get to shooting

[islandermyk]

That looks like it's piston driven... nice!


Thanks for sharing [Beer]

[El Caballo Loco]

Nice.

I want some pics of that case!

[mikeh1911]

let us know how she runs. I have been thinking about one of these. Have you found any place to buy cheap ammo?

[mestes]

Sg or buds seem to be the cheapest place after shipping. 315 to 319 for the sealed case. 2160rds

So stopped at the grasslands on my way back from cheyenne today. It was windy but below are my groups. They were fired from one knee in the wind with a brand new aimpoint m4 that I was trying to sight in. This first pic was 30 rounds playing with the adjustments. The second was my second 30 aiming to the 12o clock of the center. I kind of gave up being it was from the knee in the wind but not to bad. Shots were taken from 50 yards out. Not one problem.

I can see them can you see them now?

[mestes]

update the New frontier armory lower broke the hammer after 93 rounds! :(

[jreifsch80]

How did the lower break that hammer? I don't know ar's that well or did I read it wrong?

I believe these are plastic hammers and triggers. The hard primer on surplus 5.45 requires a stiff spring and this puts extra stress on the hammer.

I am building out a CavArms lower for a 5.45 upper and plan on using a Rock River lower parts kit. I hope this will help me avert the problem here.

[jreifsch80]

Oooooooohhhhh I just noticed he used a complete n.f. Lower. I was worried about mine because I want to do basically the same but my new frontier I bought is a stripped lower, I'll set it up just like my a1 carbine and use a rra lower parts kit too. Plastic FCG huh? I didn't know those were made, I guess im too used to ak's where there aren't even aluminum parts inside the receiver let alone plastic

Hey Rachael, get with the times, Plastic is everywhere, hell i done hear theys got some indoor like plumbing in houses, now a days

[mestes]

Ya talked to new frontier and they say its cause huldra and adams arms don't us a mill spec bolt. They are mailing me a blow back hammer to replace it that is narrower and should not have this problem. They have a video on youtube where they fire off 75k rounds really fast with no problems. I will look for the video. But sounds it was from the none mill spec bolt.

Why couldn't you just replace the whole fire control system? I swapped out all the plastic interiors and kept the 5.45x39 spring from the upper set I purchased and it works just fine on my LW15 lower.

[mestes]

I guess you could I switched to mill spec lower and pws buffer tube and geissle trigger in mine. My friend that has two of the huldra piston uppers in the 556 with the lw15 lowers did just that he switched all the plastic lpk with metal and is over 600rds without a problem. And my buddies dad that has one of my lw15 lowers hasn't had any problems with it on a rra upper 556 upper. Guess I just had bad luck but I would at least switch the fire control group.

[Kaiser.Shooter]

Do you use a pmags or a 5.45 mags?
I've heard a lot of FTF's related to the magazines

[Dr_Fwd]

Pmags doesn't work with 5.45

[mestes]

I had two first gen pmags work perfectly. But others then those two specific mags no other mags I have tried work. Other gen 1, gen 2, lancers. I could not bring myself to cutting up a window one to try it. So I went to cproducts mags now and I just make sure the feed lips are the same. That was the only problem I have had with the cproducts. One side of the lip on one mag was a lil to high. Bent it down to match the other and now flawless. So one lil tweek to one mag and other 34 work fine. I plan on just sticking to the cproducts then messing around with others.

[mestes]

With the piston system I was getting bolt bounce back giving me soft strikes. So switched to the stiffer flat wire buffer spring and now works fine with my giessle trigger. For my non piston one I have not had any problems with just running a wolf powerspring in it.

here is a dry pmag test

From my experience - pmags don't work with 5.45. I was able to feed 8rds reliably but that was it, i have no idea how that guy on video did 20rds... Oh, and I actually fired them not dry cycled.

P. S. I've Just tried to load 20rds into ge3 Pmag and dry cycle - didn't work....

it seems to be hit and miss, another vid this time live fire 20rds: http://www.youtube.com/watch?v=2OhDiVZiDkA
