Ruger SR-762

Looks like a well thought out rifle with two stage gas piston system. Iron sites are a nice touch.

Might be getting one of these. ::thumbsup::

Wow, looks like a sweet platform, and the bigger round (something desirable there) would be nice.  Nice shooting report to, and I think we all agree on the warm bolt/hot barrel debate, I guess the only open issue is how much of a pain in the butt cleaning the gas block and regulator is?

Can it be any worse than an M-14/M1A? Brother has the Sig 716 with gas piston driven bolt. He hasn't complained. But this is a bit more complex but I imagine it just takes time getting used to it.

That was my first thought. More pieces=more likely to break.
But, I think that would be overridden by possibility of a quick second shot.

Without defending Ruger, I'm certain that unlike so many that rushed their designs to get into the market, they took the necessary steps in design phase to test everything and upgrade materials where needed.

I'm in the market for an AR, and I thought about going for an AR-10 clone.  Skip all the debate about 5.56 bullet weights and barrel twist rates, and just go straight to 7.62.  No debates on that one.

But I do sort of want a proper mil-spec AR-15, and I'm currently leaning toward the Bravo Company Mid-16.  I currently have a DPMS Sportical, which is a fun range rifle but it's not a good SHTF choice for a variety of reasons.

I'm still a bit "meh" on the whole piston fad.  I prefer a direct impingement AR.

If it goes bang each time you pull the trigger, what more could you want?

I'm still a bit "meh" on the whole piston fad.  I prefer a direct impingement AR.

And yet many prefer the piston operation.

I don't know enough about the AR-15 to argue either way.

The argument goes like this. Direct gas impingement will eventually after many rounds fired begin to heat things up and begin to screw with the accuracy. Fouling was also a concern which was why the Garand rifle and the Springfield M14 were piston operated. There have been tests for validity but even so the M-16/M-4 variants weren't giving anyone so much trouble that they abandoned them. On the other hand the larger round uses a larger charge so it was assumed that it would gum up faster.  Almost forgot to mention the gas piston has a small weight penalty to contend with making a rifle heavier

Get what you want and are comfortable with, you won't be spending so many rounds that it will make a difference.

From the experts at Stag Arms:
Quote
The direct impingement has proven itself through the years on the AR-15 platform and replacement parts are inexpensive, easy to obtain, and generally made to a set “mil-spec” standard.  Due to the hot gas from the fired cartridge being redirected into the action it will quickly heat up and become dirty requiring a cool down period before the bolt carrier can be removed from the rifle.

The action of a piston rifle remains cool and clean, even after shooting 100 rounds in rapid succession. The bolt carrier can be removed immediately and held in your hand without burning yourself. The trade off for the action staying cool and clean is that you will experience snappier recoil when shooting which makes the piston rifle a little less accurate, especially for follow up shots. Finally, piston system parts are not interchangeable between manufacturers due to there being no set standard and the use of proprietary pistons and bolt carriers.

Glock You cannot go wrong with a BCM AR.

I built one with a 20" BCM upper and their full auto BCG. I put it on a Spikes lower with palmetto QMS LPK with a A2 stock and it is an outstanding gun.

I have found when I use red lithium high temp wheel bearing grease on my BCG it runs flawlessly and cleans up easier. On my present build I am either going to buy a Ni-boron BCG or a Black Nitride one as prices have come down greatly on them.

If you feel like building your own, BCM has a sale going on where you can get a  BCM Standard 16" Mid Length Upper and their quality full auto BCG for $439.00. If they are out of stock they usually will be back in stock within a week.

Palmetto State Armory also has good deals on their AR's but it is hit or miss.

PSA seem to be of excellent quality as their barrels are made by FN.

I just completed a build using a PSA 300 AAC Blackout upper that I am dying to try out.

Thanks for the info Magnum.  The AR is still a source of confusion at times.  I really wish everything wasn't carbine, because what I really want is a semi-auto clone of a M16A3.  I don't plan on doing house clearing drills, so I'd really prefer a rifle length.

Yeah I have a Winchester 1300 Defender for scattergun vermin control.  A full tube of #4 buck is the reward for anyone dumb enough to B&E here.

Here are photos similar to the ones I built:

BCM upper, Spikes Lower with 20 inch govt profile barrel, 1 in 7 twist



DPMS upper, Anderson Lower with a 20 inch Heavy Barrel, 1 in 9 twist, even though this is a very accurate riffle I would not recommend the heavy barrel as it does get heavy when trudging through the woods.



Also you cannot go wrong with the gold standard Colt M16 A4

Sorry Warpmine I did not mean to hijack your post, the Ruger does look like a awesome gun that has peaked my interest, Thank You.

Those are fantastic looking rifles Magnum.  I understand the advantages of a shorter weapon, but I just think the classic M16 style should not have become passé.

Maybe building is the way to go, versus buying a complete rifle.


ETA - Magnum what do you think of the FN-15?  I didn't even know of this rifle until today.  Basically FN's civilian version of the M16A4.  http://www.fnhusa.com/l/products/carbines/fn-15-series/fn15-rifle

Hi Glock I think the FN - 15 is a Awesome gun from what I have read and heard. FNH USA is the current manufacturer for the M16A4 and M4 series rifles for the U.S. military.

Here are a couple links you may want to look at when you have time.

http://www.ar15.com/forums/t_3_118/630342__ARCHIVED_THREAD____fnh_fn15.html&page=1

http://www.thetruthaboutguns.com/2014/01/foghorn/new-fnh-usa-fn-15-modern-sporting-rifles/

FN is the company that makes barrels for Palmetto State Armory if you are considering building your own. For Example:

Keep me updated. I will help you in anyway I can especially if you decide to build your own, I will warn you however once you build one they tend to breed like rabbits ::thumbsup::
