I pieced together an AR

[budlight]

20 inch stainless flutted 8:1. I had a bunch of spare this and that for future repairs, but I got to thinking that all I'm missing is Hogue butt stock and grips to make something complete.

Home made light weight hammer. Drilled and ground down. lighter trigger springs and polished catch so it's much better than a Mil Spec that it started out as. I spent hours on the wire wheel then polishing wheel making the barrel beautiful. I preferr slick sided uppers, but I had this forward assist model in a box for 15 years. Wide nice charging handle new in 15 year old box. A extra Nickle boron full auto bolt. The counter stike red dot sights. Tall easy to grab take down pins. Rifle length gas tube with .072 flash hole for shooting 55,000+ psi 5.56 rounds. I've had similar barrels really shot nice with 69 gr HPBT over 28 grains of 2000-MR for 3100 fps. I actually got the best 200 yard groups toned down to right at 3000 fps. My last 8 pound jug. You can't find alliant powders around here. sticker on it says $179.99 LOL We must have 100% inflation on the price today for 8 pounds.

Hey. I was looking back on what I paid for various powders, primers, etc from basically 2020 or right before then and man, what a truly sad horrific state. I know you can't do much about spilled milk but my lord they are putting it to us on virtually Everything and I do mean Everything. Oh and extra parts, very good idea and smart plan. Ask me how I know - been burned more than once until I finally wised up.

my extra parts go fast. i usually keep 10 complete lower small parts (springs, detents including safeties, bolt catches and mag catch/releases). also keep 2-4 triggers (cassette type) as acquired on sales. i never know what cartridge i desire at the moment, so that's always last. with ar's i'm doing some "not-so-usual" cartridges (6.5prc, 7saum for now) and collecting 300wsm necessary items for a build (dies for now). my "gotta have" is a ar458wsm. with the right bullet weight and powder from a 20" (might require a 22") it could produce 5k of muzzle energy. always nice having extra parts! hogue is 1 of my go-to's..nice build

I'm a 458 person. I don't think that I would pull the trigger on a 5000 foot pound AR! My 458 Barnes American launches 405 grain barnes X's at over 2200 fps and it makes other mag rifles feel like wimps. I can take about 20 shots bench resting and I'm done for the day. The butt impact kind of rotates me even with a shooting vest on and I feel like I need to see a chiroprator

 

[ARlife4me]

I don't think I'd want to pull the trigger on a "5 ton" also. 5k, yes.

405 gr @2200 + 4353 foot pounds

my 458 win mag shooting 510 gr at 2140 just breaks the 5000 foot pounds. 26 inch barrel and a safari gun.
