Gas piston operated AR

[BlackJack]

Ok, I know that the Sig 556 uses a gas piston operating rod system. Are there any other AR style rifles that use a gas piston rather than direct gas impingement? Also, does anybody know of anybody making an AR10 (AR in .308) that uses a gas piston?

Thanks,

here are a few:

I think this uses a gas piston also:

I'm a fan of the LWRC design.

I voiced some opinions here First Experiences with LWRC - A Discussion on Gas Piston Uppers

And did a comparison between my DI and Pistol ARs here

If I got one I'd get the LWRC as well. They have been developing a .308 version but I don't know if it has been released yet or not.

Bushmaster is now offering a conversion kit to convert carbine length gas systems to gas piston:

Well I hardly call it an AR variant but the Kel-Tec SU-16 uses the same mags, is chambered in 5.56 and is gas piston I think.....

I have been looking at the SABRs for awhile now. Was going to order one until I saw the $99,000.00 dollar price tag. I thought that was a bit high so I wrote LWRC. This is some Andy's at LWRC reply.

Actually, that is the correct price to purchase one of the two prototype SABRs that we have built. All kidding aside, the SABR is not available for commercial sale, but we wanted to give info on the web store, and the software that we use requires us to enter a price. At $00.01, we got hundreds of orders for one penny SABRs. The hundred thousand dollar price has dissuaded most people from ordering them.

We expect the rifle to be priced at approximately $3,500. Options are not available right now as the guns are not available for sale. We expect to begin shipping commercial models at the end of August.

Let me know if theres anything else I can help with.

And so the wait continues. It is hard to imagine a mere human such as myself hitting anything at 1000 yards but it should be fun trying.

Barrett is producing their REC7. A gas piston operated M4 platform chambered for 6.8mm

I just built one for my AR.
It was working great until my bolt key, that I had modiified by cutting the gas tube back, bent.

Now I've got to make a solid bolt key from scratch and harden it. It'll be much tougher than the modified one anyway, so thats a good thing.

I couldnt find a spring to fit it, so I took some .040 Piano Wire and wound a spring on the lathe. It worked good too.

Its basically an 400 dollar ARES copy with a few differences but other than time it was free.

Ruger uses what they call a fixed gas piston in its Mini 14 and 30. That's why they are so dependable. Really, the only reason to clean the weapons after hundreds and hundreds of rounds put through them is to clean the bore. Add a heavy barrel and some trigger work and you have a carbine that is capable of MOA accuracy and the dependability of an AK. That's why most people who shoot 'em , love 'em. dgang

I have an LWRC M6A2 on order. Hopefully I'll have some firsthand experience soon! But from everything I have heard I'm making a good investment.
