re: Official AR-15 thread

To be honest when I bought the 700 I bought the stock and switched it before first shot so I have no idea how it changed if at all. I haven't had much time with it yet...got it together and sighted in to hunt with last season. I want to go back to the range and see what ammo it likes best and then see what it will do. I need more free time in my life

Starting a 300 blackout "pistol" build. We'll talk cans later but my question at the moment is the barrel. I put an Odin Works on my 223/556 build. Really accurate. Should I spend $300 on a barrel for a rifle that will not be long range? Or buy a $100 PSA barrel? I'm not in a rush to get in finished so the price doesn't matter but if I don't need to spend that much on the barrel I may not. The plan for the rifle is throw a red dot on it and hunt coyotes and pigs with maximum shot of 75 yards.

I would not spend $300 on a 300BLK barrel as they are not touted as the most accurate round and inside 100 yards even an 8 MOA barrel is likely still going to kill hogs/coyotes. I also would not buy a cheap PSA barrel. I would buy a US made barrel from a company like Ballistic Advantage or Faxon. And if I was going to really do it my way 300BLK would be the last cartridge I would choose for a gun you intend to hunt with, or really do anything with. It doesn't do anything better than any of the other 4 main commercially supported cartridges with the exception of suppression and having a catchy name. For hunting with and AR-15 I would suggest 6.8 SPC or 6.5 Grendel, with a heavy lean towards the 6.5 since it can do everything the 6.8 does and double the range. Sure a 300BLK can be used, but I think you will be a lot more pleased with the performance of the 6.5 or 6.8

Appreciate the advice. I will look into those barrels. I get what your saying about the 300BLK. I am trading some stuff with a buddy and will be getting an AR that he built. I don't want another 223 but the plan is to convert it to a 6.5 grendel. I'm wanting a pistol as well and decided on a 300BLK because I'd also like it suppressed. I like to have a different calibers.

I would absolutely do a 12" 6.5 Grendel hog hammer. Even in a 12" barrel the Grendel, not schockingly, smokes the thrown-potato-esque ballistics of the 300BLK.

Interesting. I wouldn't have thought a 6.5 grendel as a pistol build. Looks like I'm going to get a 12" 6.5 grendel pistol. Will still convert my new 223 to one as well.
Can you tell me a couple of companies you would go with? Grendel barrels are so hard to find I'd like to have a couple of companies to keep an eye on.

Thanks, appreciate it. Could you point me in the direction of what buffer system I would need for a 6.5 Grendel pistol build?

Intrested to see how this goes. Been thinking about a 6.5 or 6.8. How is ammo availability? Haven't looked really.

Ballistic Advantage just released their lineup of 6.5 barrels and Mark at Precision Firearms (not the shitty BR range) is spendy but makes a damn good 6.5 barrel.

2nd on Precision. I went with JP for my 22". I wouldn't hesitate to go with Lilja, Odin Works, or any of the listed above though.

Prop, I've decided to continue with the 300BLK build. But will be converting another 556 to a 6.5 Grendel. Debating whether to order another lower and make it a 12"' pistol or go with a rifle barrel. What would you say is the range on a 6.5 Grendel in terms of accuracy and hitting power? The farthest shots i can take where I shoot, is about 350.
