What is better?

Postby iridium-192 » Sun Nov 27, 2016 12:22 am

Well, I'm still indecisive & can't find an answer to very important question for ANY CALIFORNIAN... This question is, "what should I buy?"...
1. AR 15
2. AR 10

I love both cartridges, love both rifles, don't have a budget for both...
What is better?

Here is a video, I'm watching right now, hoping it will help me to decide...

What is your opinion? I would greatly appreciate any input & help!
Thank you! :thumbup:

Both have advantages and disadvantages . My personal opinion would be to get the AR-10 , in .308 caliber . You could then purchase a .556 Upper at a later date , and then have both capabilities .
There are those who are enamored with the .556 , but I'm not one of them . There are those who are enamored with the AR platform . I'm not one of those people , either . Trying hard to be objective in answering this , cause frankly , I think the AR platform is the biggest POS ever devised by man-kind . Sucker's had more "EC's" done on it than the space shuttle , and still leads the world in jams , mis-fires and malfunctions . If you are getting a piston driven gun , similar to a AK / SKS , then good on ya . :thumbup: Don't recommend a gas impingement system , though . Like a high maintenance woman ... :thumbdown:
The AR-10"s seem to have less headaches ; even in the gas impingement system guns , due to the larger caliber cartridge recycling the system .

Carried a M-16 for four and a half months in Nam , and when the third one jammed in the same fire-fight , I was lucky enough to have a SKS within reach ....I still have the SKS . I'd use a AR platform gun , if forced to . Until I could replace it with something I'd trust my life on .
That's my opinion . Hope it doesn't ruffle to many feathers in the "God Gun" crowd .

I agree with Grindl on the AR-10 platform. It opens up the possibilities that are almost endless. I wonder if, with a modded boltface and the right mag, a 7.62x54r might be possible? A domestic Dragunov!! :D :D

To convert a AR-10 for 7.62x54r , you would have to do a bit of a reamer job on the chamber , as the54r round is longer , and has a greater amount of taper in the cartridge . But I'm not sure about 'modding" the bolt , as the .308 cartridge is "face-held" by the bolt-face ,and locked up by the bolt lugs . And the 54r is pressed up against the breech by the case rim . Guess it could be worked out . The other question would be : Is the bolt diameter large enough to facilitate the diameter of the case rim on the 54r case , and not loose part of the locking lugs in the bolt .
In looking at the problem , the chamber mod is do-able , but I think you might have to machine a whole new bolt to accommodate the 54r case .

Somebody makes a AR in .300 BLK , Iridium . I think it's Sig-Sauer . That would be splitting the difference between the .556 & .308 models . Something else to think about . :crazy:

I'm not sure the receiver is strong enough to handle the 54R pressure, you might need to seriously mod the buffer tube area, and I'm not entirely sure the castle nut receiver connection would be robust enough for the pressure generated by a 54R cartridge.

BUT that being said doesn't mean someone couldn't come up with a material that is strong enough. Hmmmm an AR steel receiver sounds interesting.

But back to the question at hand how about a 24 inch AR10 target rifle?

I like the idea of AR receiver made of steel...

DUH ! Never even entered my mind about the receiver being alloy instead of steel . There are some guys building AR-10 / 24" & 26" guns for L/R & tactical shooting competition already .
I've seen a couple of them at the 1,000 range at Ben Avery . They're still working out the bugs for their loads , and not very forth-coming talking about the guns at this point . :shh: Ancient Chinese secrets ; I guess .

I think a steel receiver is totally doable. Just need someone with a laser scanner and the CNC mill and away you go. Magazine might be a bit of an issue since the rim on the 54r causes the round to pitch more. It might end up looking more like an AK magazine.

BUT an AR-PSL sounds like so much fun to design and build.

Well back to Dmitry's original question, I think it would have to be the .308 based AR10 simply due to the fact there are so many variety's of .308 on the market and it's greater knock down power. But the lowly .223 is not without it benefits. Especially when you consider a multi cal receiver that can fire a 5.56 out of the same barrel.

.308 more knock down and larger variety of projectiles
.223 plentiful and cheap
.556 Higher velocity
