KAK 358 Winchester 19" Rifle Gas AR-10 Barrel- Stainless

Had to do some work on the barrel extension with needle files to clean up the edges and a little polishing. Feeds Speer 180g FP, 220g FP, 250g SP and Hornady 250g RN without issues. One big ragged hole. P- Mags were a little tight when loaded but no problems. Glad I got this barrel. Shipped fast.

I was on the waiting list for this one. If I didn't get the notification it was in I was going to get a GMB blank and cut my own. Since I 've already got 2 blank in the queue having this one become available saved me some lathe time. The barrel is exactly as described. Looks good, lands nice and deep. Recommendation : buy!

I have yet to fire the gun, but last night I mounted the barrel and built the upper with no issues. Barrel plugged in snug but easily. I really like the matte finish for future hunting use. Gas port has two dimples on bottom to give a "home" to gas port screws. Packaged well.

When I stumbled upon this on KAK's website I was immediately attracted to it because I was not familiar with the cartridge and did not even know it was available for an xx 308 build--so of course I bought one! As far as I know--KAK is the only retailer to make these as a regular production barrel--and at a budget price at that. Upon playing around with some ballistics calculators--I quickly realized what a stupendous caliber the 358 really is and the only huge question being how the 358 win has languished for so many decades. Everything I read warned of 300 wm level recoil and "limited to close (200 yd) range woods gun use only"--both of which I think are COMPLETELY UNTRUE! With a decent brake mine recoils with very little noticeable difference with a regular 308--and while not the fastest or flattest-shooting bullet around for an AR--it still delivers PHENOMENAL energy to longer ranges. With the right bullet and the right shot I bet the 358 can drop any game on the planet at closer ranges--but that's just a guess : )
