6.8 spc barrel length ????

I have a Bison BSP cut down to ~12”. Can’t say I’ve shot it at 300-400 yards though. ☹️
 
Any knowledge or feedback on PSA 18" MID-LENGTH 6.8 SPC II 1/11 STAINLESS STEEL 15" LIGHTWEIGHT M-LOK UPPER WITH BCG & CH complete upper ??
 
PSA puts out decent stuff. If the price is right, go for it. I ponied up for a Bison Armory upper because, well mostly ‘cos I could & it was the “nicest” 6.8 in my price range. No complaints at all about my wife’s PSA 5.56.

Honestly, I’d snatch it up while you can if you can swing it. It’s a helluva round, but apparently not all that popular. Get set up for it while you can, if it’s what you want.
 
If (1) you’re anywhere around Meck Co and (2) have an SBR lower or non-stocked lower and (3) bought the 18” PSA upper…I’d let you borrow my 12” barreled upper to compare if you’re interested.
 
I have a Wilson Combat 11.3” stainless 1:11 twist that I hunt with. It shoots factory ammo sub MOA at 400 yards.

It is a solid upper, I have one. Holds about 1 MOA out to 300yds, the furthest I’ve shot it. If you’re REALLY trying to squeeze the most yardage then the 18” barrel will be one of your better options.

I will say, if you’re looking for peak performance from this caliber then you must hand load for it!!!
 
I've got an 18" ARP barreled 6.8 that's also extremely accurate. It's the 1-10 3r rifling and likes bullets 110 grain and up the best.
