    twist rates and short barrels

    Greetings Forum, I'm looking to build a short barrel AR for fun and shorter range hunting, I have an Armalite AR10 that I want to slap a new short barrel on and swap the furniture. Looking to hit elk and steel targets out to 300 yards at the furthest. I have a 7mm mag bolt gun so a short woods rifle is a fun concept. Armalite has their 13.5" competition upper in 1:10" twist rate, while a 13.5" barrel has a 1:8" twist rate. Now I've been told by reviews on the Federal website that shorter barrels do better with lighter bullets, which also need a gentler twist to get stabilized. I've also read that over-twisting bullets on a .308 AR is not too detrimental for accuracy. All the charts I've seen show that a 1:8 twist rate is needed for bullets heavier than 200gr, while the short barrel AR's excel with bullets in the 150gr neighborhood. So my questions are as follows, what's the reasoning for cutting such a fast twist into the barrel and should I even be concerned about it?

    Tensioning works correctly... More than 90° cant either direction and holds tension throughout...

    Indeed, more than 90° of it! Milling the radius the old-fashioned way... Before sanding... After sanding & before bead blasting... After bead blasting & before painting...

    My grandma would simmer the squirrel in a pot of gravy all day then serve it. I pulled the head out of the pot once with its little squirrel teeth and face looking at me. She said that was hers and broke the head open to eat the brains. Damn hillbillies will eat anything. Racoon and groundhogs were on the menu also.
  12. rest of my shite hit this week, loose assembled everything, looks amazing and all makes more sense now. might still have a prob with the fitment between the poly lower and the Aero upper but we'll see once I get it all together if I really have a problem

    Vltor 308AR spring..........

    7" internal depth AR15 carbine receiver extension, mil-spec, from a reputable vendor, Armalite EA1095 spring, 2.5" buffer with a stainless steel body. We'll see what it looks like on Monday, when I get to work and get hands-on. I'm hoping the stainless body adds alot of weight, over the traditional aluminum body. I'm hoping this little 2.5" buffer is pretty close to 5.4 oz, like an H3 buffer. I'll slap it on the gram scale and find out.

    Matt's hitting the hard stuff. I see the Cheerwine in the picture. Your modification looks great.

    Sounds like I have it sorted out thanks to you 98. I have a 16" mid and 14.5 mid 308ar builds and seem 100% fine with 5.4oz rifle buffers. When changing the 14.5 over I notice PWS sells a 6.9oz 3.25" carbine buffer I might go with. Depends on how it responds to a suppressor down the road but that's another subject. I'm interested in your new adventure with a different system. Any hints on what it is?

    Drum Circle Haze DIPA, Catawba Brewing Morganton N.C. Hops, hops, and even more hops! Very similar to those New England IPA's from Tree House, but not as smooth. A hint of citrusy fruit but with a piney somewhat dank finish. I have no intent of attending the Asheville drum circle event with all the hemp hippies but I will be enjoying their beer!
