One of the reasons that the 6.8 gun sits in the corner gathering dust is when it dropped out of the mainstream, ammo got a lot more expensive.
It costs as much per round as .308 Win.
But it's important to remember that every AR maker, except Colt, had a 6.8 in their lineup at one time.
It was that close to making it and sticking.
It's a shame, because it's a damn fine shooting round.
I cannot bring myself to get a .300 Blackout because I am the kind of idiot who'd get my magazines confused and try to fire a .300 out a 5.56 bore. Lots of ka-booms from that.
One place that 6.8 and 6.5 are way better than .300 is, even with a weak crimp, you're not going to accidentally misfeed the wrong round.
Magpul doesn't make them anymore, but when "sand" color Pmags were available I bought a bunch and dyed them bright orange (160F water, add orange and yellow Rit clothing dye in 80/20 proportions) so I could visually differentiate 5.56 mags from 300BLK. Never did find a way to make them tactilely different, especially with gloves on. The best seemed to be "dots" of silicone caulk or using the caulk to hold "ribs" of 3/16" X 3/16" plastic on the sides with short pieces (like morse code dashes) on the front and back (heat and bend to fit before gluing with the caulk). I still lose sleep over the possibility of mixing them up, especially around people who "nein sprechen sie AR-15."
ReplyDeleteI'd go more extreme, metal magazines for one round, plastic for the other.
DeleteWe dyed a LOT of those Sand PMAGs.
DeleteMagpul makes a tactilely different magazine for .300 Blackout. https://magpul.com/pmag-30-ar-300-b-gen-m3.html?mp_global_color=118
But you can still get the wrong rounds in the wrong magazine and get them in the wrong gun.
I don't think I'm meticulous enough.
