NICE Rifle!

I’m a huge fan of 7.62x51mm/.308 Winchester as a defensive, hunting, and all-round useful cartridge. Put it in a handy battle-rifle and it can easily be deployed for all sorts of uses.
My Go-to Rife happens to be a mish-mash of FAL parts.

Looks like Bluesun went another great route with an AR-10.

Hop over there to look at pictures. Also he has a LOT of good questions that I can’t answer, maybe you can give him a hand.

Slick gun dude! I suspect you’ll be VERY happy with it!

    I like it, anyway. Course, haven’t actually SHOT it yet…

    This is where we FAL owners get all snobby about having a piston gas system. 😉

    It’s also where I start mumbling and being evasive to questions about my ARs…

      My opinion that is worth precisely nothing is that a Gas piston beats a direct gas system overall in a gun design….but if you want an AR platform gun bolting a gas piston onto a design specifically designed and fielded to be direct-impingement will likely cause more problems than it solves.

        I’m going to go purist on you here. Yes, I know this is up there with the clip/magazine debate.

        The gas system on an AR is not, I say again, NOT direct impingement. If you want to see DI you have to look at the Jungmann and MAS-49. In DI the gas comes from a tube and strikes a spot on the bolt carrier. Gas velocity is imparted to the bolt carrier directly.

        In the Stoner system the bolt is the piston. The originals had the gas entering from the SIDE of the gun not inline. Gas enters the bolt carrier via the gas-key and then expands behind the bolt. Note the gas rings on an AR bolt. The bolt can’t move forward here, so the bolt carrier moves back, doing the normal unlocking thing.

        It’s an elegant design! What it does is put all of the action and recoil forces in the same line with the bore. An AR goes straight back, no rise from off bore forces giving torsion to the movement. Because it’s combining otherwise separate parts it’s also a lighter design.

        Now, dig out your FAL. Notice the piston is above the bore? That means there’s a moment arm equal to the distance between the centerline of the bore and centerline of the piston. It’s small, but there’s a lot of force there. That will cause barrel rise. Then take off the top cover and work the action. Notice the rat-tail on the bolt carrier changing angle? That changing of direction of the energy also induces twist, a cyclical one in this case as it first shoves down in recoil then shoves up in return. Also notice the face of the lower where the rat-tail goes into the stock, is there some pitting? That’s from the bolt carrier slamming into it. Another transfer of energy off bore-line (up rise again too). Stoner was trying (and succeeded) in taking all of those off bore angular forces out of the recoil and return strokes.

        System design is more than just how the gas actuates it.

        I totally agree about slapping a piston onto a Stoner and claiming all things are solved.

    Tampons in the man-cave area?

    What creative non-menstral use have you found for them on your gun bench?
