New Buyer curious about AR designations M3, M4 etc

Featured Replies

Total AR newb. I know what I like and what I want it to look like, but I have seen 2 designations that look almost the same but be different designations and different prices.

 

For example

vs

I have also seen a Colt M4 that looked exactly the same for $950.

 

I am ready to pull the trigger ASAP but a little confused.

First one is a 1/7 twist barrel second is a 1/9 twist heavy weight barrel..

Neither of these weapons are compliant to nj laws with out secondary mods too.

I know the collapsible stock is out.

I also assumed 1/9 twist since I heard it is designed for most bulk ammo (55gr).

 

I just want a short simple looking AR, not into 100 toys, maybe a red dot, but I like iron sights. My only exp was with a Sig 556.

Pinned Stock( sucks not knowing without holding rifle first),no 30 rnd mags,bayonet lug and comp must be pinned and welded in place

Edit last post to you need to have a muzzle brake nothing considered flash hider. They appear to have a standard a2 flash hider on them.

Yeah, I have pondered these evils, I have actually held off on the chance that NJ came to its senses and eliminate the folding stock from its evil features list but it will never happen. Went to RTSP and saw a Stag that looked interesting but figured I should wait and make sure I get what I want.

Colt is superior to stag but you will hear people say they are all the same..

I have heard the same, I will be lucky if I put a 1000 rounds through it but I always wanted one.

build your own...

As daunting as it may sound, the AR platform is basically lego. Get your lower receiver, mate it to an upper, select your stock, get your bolt carrier group and you are done.

 

Try it yourself here: http://www.ar15builder.com/ It really is that easy.

I've been researching this stuff myself, and have been trying to find something very particular... maybe someone here can point me in the right direction...

 

I held my buddy's Bushmaster AR, absolutely loved it. Felt like it was a part of me, very comfortable, very fast. What I'd like is this AR platform, but in 7.62x39, with a piston system? From what I gather, the main problem with the "7.62x39 ARs" is the mag issue... with the cure being to build a lower that accepts AK mags? Anyway, there are a few AR/7.62x39 models out there, but none that I can find are piston driven?

why would you want a 7.62x39 AR..

I really like the AR platform, and I prefer the 7.62x39 over the .223. Simple really.

 

I see Larue makes one, but it's $$$$$$. It seems .223 piston is easy enough to find, 7.62 DI is easy enough to find, but 7.62 piston is not. I could probably easily settle for a 7.62 DI, the piston would be nice, but it's not a deal breaker. I'll keep researching.

You could probably find a piston conversion kit for it. I know they make them in 6.5 Grendel, so they might make them in other calibers as well.

How about the 300 blackout? Supposed to be a 7.62 bullet designed for the AR platform.

Honestly - Don't be afraid to go with a DI system. For what you'll be doing with it, don't waste your money on a piston system.

Yep..DI has worked on the battlefield for 40+ years in the M16 mold...is it perfect?...no... but its service life is a testament to its function.

This. I used to be a DI hater as well, but now I run a 14.5" mid-length DI AR that I have never cleaned, and I've never had problems with it.

Not interested in the Blackout's funny caliber. And I think I will drop the piston requirement... my buddy with the AR (DI) says his next purchase is a piston AR, I just assumed they were better... did some reading, and DI is just fine with me.

 

So- now to re-look at all the retailers offering the AR platform in 7.62x39...

I would definitely do some research on reliability of manufacturers. I was doing carbine training in Sept and the guy next to me was running a 7.62 and couldn't get through a single magazine without a malfunction. He had to use the instructors ar to finish the class. I don't know if it was the ammo(steel cased) Mag or upper but he really suffered through that class.

 

I've heard lots of reports of bad mags.

Very daunting, anyone ever do build an at with Anthony.?

From what I can gather, the ones that are designed to accept AK mags function flawlessly, it's the ones trying to make their own AK mags where all the problems start.

Fair enough. Not trying to dissuade you. For what its worth I do think they were the ar style mags.

ok... ill try again.... why do you prefer 7.62....

 

it definitely packs more punch... but drops like a stone.. and is useless at any significant distance..

And I will try again...

 

I won't be using it at any "significant" distance, and at the distances I would be using it at, it packs a bigger punch, it's a round to kill, not to wound. Not to mention I've already got a rifle in 7.62, and would like to use the same ammo. If I had wanted a .223, I would have purchased one. But I didn't, so I didn't.

dont bother. if all you want is a plinker that will see occasional use, just buy a bushmaster, or stag. there is a 99.999999999% chance you will NEVER use it at or even near its limits. either brand will more then likely never jam, and if it does, youll only be sitting at a bench at the range anyway....so 1 in 1000 rounds it may jam, so you get experience clearing a malfunction. big deal.

 

unless you flat out plan to beat the shyt out of the gun to purposely find out its limits, there is NO reason to spend twice the price on something that will never be used to its full potential. thats the same thing as buying a veyron just to have the fastest car in the world, and only use it for commuting to work and grocery runs.

 

my first AR was a stock bushmaster, only shot at the rang (as you plan to do).. never jammed, no malfunctions. i then added a stag flat top upper, and did some classes and training, running silver bear almost exclusively. ZERO jams, no malfunctions. i then added a used, pieced together DD/BCM combo upper on mostly an impulse buy. still on the same, original bushmaster lower. i did not NEED to upgrade from my stag upper, since i never, ever had a problem with it. no jams, no malfunctions, no problems with it not being a free float handguard, nothing. i just found a decent deal and bought it.

 

despite what some people think, there is absolutely no reason to take what the chest-beating rollmark snobs say as gospel. the only advantage youll have of buying a fancy manufacturer over a bush or stag, is you may sleep better with a shyteating grin on your face and have a lighter wallet, while the gun sits unused 360 days of the year.

at the distances I would be using it at, it packs a bigger punch, it's a round to kill, not to wound.
