glfa 300win mag info

I might stay away. It does look cool, but the fit and finish on my 308 are sub-par. If they havent perfected the 308, then im sure the 300 win mag is lacking as well

I have a glfa 5.56 carbine . I bought it to use in 2 gun matches . I have run around 2500 rounds through the gun and not had any issue's , but everybody sell's a 600 dollar AR 15 these days' , look at the volume of Palmetto state's sale's . A 300 winmag its a horse of a different color and having something like that next to your face is a big deal . While I can't say anything bad about glfa from personal experience I certainly would be extra cautious especially at the price point . Maybe let your ex-wife shoot it first .

For a cheap semi, I'd err on the side of caution with that much power a few inches from my face.

So higher end companies can’t get 300WM right, but you think a bargain bin $1100 rifle will be good? $1100 308 gas guns aren’t even worth owning.

sometimes. look at the cheap 50bmg rifles mark serbu makes. only head one of them kabooming and that wasn’t the guns fault.

No but it almost killed a guy when it did explode and that is the gun's fault.

There's been more than one Serbu have an issue. Cheap guns are trash. If you have $1100 to spend on a semi auto buy an AR-15, it's the only way you'll get something for that price that isn't a piece of shit.

No it wouldn't. Go buy one of these turds and tell us how it is.

ur point?? any barrett would have went kaboom too in that situation

Likely... but it wouldn't have sent a steel puck at mach Jesus towards your face.

no just a bolt, carrier, and aluminum fragments. when you get to those pressures anything can happen.

Take a look at what well designed systems actually do when they fail. They fail at pressures outside the operating window by a reasonable amount and explode outwards as much as possible. Holding a shit ton of pressure then leaving nowhere for the failure point to go but back at your face is a horrible idea. Anyway, enough arguing about a 50 BMG pipe bomb in an AR thread.

Well I happen to own one. It definitely looks better than the 308 version pictured in this thread. Hand guard and lower have no burrs. Or sharp edges. Upper receiver had some burrs. But that was simple enough to take care off. Very little play between upper and lower. Took a look at the rifling and Crown. And they look excellent. No excess machining marks. I literally went through the whole rifle. Every part was nice and tight. I did find a few nicks on the buffer. Which was from the factory test firing it. Had to install an off set Galloway precision off set buffer pin. I did the standard test on the lower. Put it on safe. Squeeze the trigger. Watch for the trigger pins to move. And they Didn’t wiggle in the least. Which is a good sign. When I installed a picatinny rail and sling attachmen. They literally fit perfectly. No play back or forth. One thing that I don’t like is they use a roll pin to hold the firing pin in place. BCG is nitrided finish. And the only thing that looks standard is the cam pin. Which I will be replacing with a POF roller cam pin. I did replace the buffer tube spring with a Tubbs flat wire spring. I also installed a Larue MBT trigger, LMT muzzle brake, Luth grip and PRS stock. Had to go with a Luth stock. Because of the longer then normal charging handle. I had to move the cheek riser back to clear. I also replaced the charging handle latch with a extended one from Strike Industries. Magazine is really heavy duty. They only offer a five round right now. I did send an email and they claim they will have a ten rounder in the future. Took it out to the range. To sight it in. Loaded up some test rounds. Every thing went great. Recoil was not a issue at all. I wasn’t going to buy this rifle after reading some of the negative comments on this forum. So I looked on the internet. And everyone that bought one was happy with theirs. Right now with my starting load I‘m shooting one MOA with 185 grain Berger VLD bullets with MP 700 powder. The powder is a bulk powder similar to Accurate Magpro. Ejection is around three to four o’clock. Brass looks like I shot it out of a bolt gun. No case swipe or grated primers. So I just loaded up some more that are slightly hotter. Searching for a node between 2700 -2950 FPS. Will update once I have worked up a load that I’m happy with.

Took it out to the range yesterday. Finally settle on 75.2 grains of MP700, COL 3.36, 175 gr Sierra Match Kings and Hornady cases. Ejection is at two o’clock. Brass looks great. No pressure signs. It is still a one MOA gun. Which is fine for me. It shot the Berger VLD excellent. But then I started to have feeding issues. Had the same problem with them in my AR10 rifles. So went to the Sierra Match Kings. It runs like a sewing machine now. Would have went with heavier bullets. But the 175 grain works well in all of my 308 rifles as well. Going to pick up a new chronograph from Garmin soon.

I'm having popped primers on 180 grain Hornandy Match but was running 175 grain Precision Hunter just fine. I'm going to try to reduce the gas with an adjustable gas block and see if that makes any difference.

Good to see the positive comments about the GLFA. I'm going to have a 7mm 08 X caliber here in December but a GLFA 30 06 is next on the list. I was holding off because the price of powder but with the election over powder prices could be dropping I hope.

With 300 Win Mag gas guns. The go to powder is H1000.

What is the max cartridge length, in the magazine, in the 300 Win Mag models?
Thanks

I did measure the inner dimension for someone else. 3.4710 inches.
Right now I have a lot of Sierra Match Kings in 175 gr that I reload for mine. Any there is a lot of clearance.

I’m assuming the 300 Win Mag chambers in these barrels have a SAAMI freebore of .000”?

No idea. You might want to send them an email. Being a gas gun I haven’t measured the jump. Mine is accurate. I full length size. And check every round with a case gauge. Don’t want to risk an out of battery discharge.

I reload for everything have, but the only 300 WM brass I have right now is Hornady.

I have a Bunch of factory ammo for my Browning BAR, but all of the factory stuff is SAAMI length at 3.330"

Before I start out...Have you reloaded any 300 WM for your GLFA, with the COAL approaching the max mag length of 3.47"?

If so, have you had any problems with feeding/bullet tip damage, as it runs up the feed ramp? (this being a single feed ramp has to help on the longer COAL loads I would think)?

Everybody maxes out their COAL in the LR 308's at 2.800+", but I'm wondering if you have any luck maxing out this available mag length?

Anyone else maxed out the 3.47" mags in these guns? Any luck?

Thanks

I loaded some 215 Bergers out to 3.440” COAL today…they fed good

Heavybuffers.com makes a Heavy buffer for these guns.

Since the “rifle” buffer is shorter in the long action ARs, the heaviest the buffer can be made is 12.45 oz., with the tungsten weights.

I’ll report back once I get some rounds down range with the 300 Win Mag.

The new Faxon adjustable gas block is the perfect block for this rifle. With 300 Win Mag AR rifles. They dump a lot of gas into the system. I definitely could see carbon lock happening fast. The Faxon block moves the gas tube. The mechanism that performs this action is independent and isn’t exposed to carbon gases. My gun is gas perfect at the moment. But I’m thinking about picking up a suppressor.
