AK-47 fitted with a 6.8mm SPC barrel?

[Darth AkSarBen]

Could an AK-47 be fitted with a 6.8mm Remington SPC cartridge chamber/barrel combination? It would have the reliability of the Kalashnikov action but with the superior cartridge firepower of the 6.8mm Remington configuration.

Such a rifle would be immensely valuable to the troops fighting in Afghanistan.

Meh .... the 6.8 is only about 300 fps faster than the x39 with about 10 grain less bullet weight and as 1bg has shown, the x39 is no slouch in the accuracy dept even out of an AK.

Personally if i had the choice of firearm to take to the sandbox, a 1biggun worked AK in x39 would be my number one.

Its been done. I have the barrel and started to do one but Its been in limbo for a while. I was planning a heavy barrel target build with a stainless barrel IMOO the 6.5 grendal is a better round and the prices of ammo are better. A 5.45 bolt can be opend up for the SPC . there are several options on mags. The AK can be modifed for a longer mag well. why be resticted to rounds designed for the AR15/M16?? a 250 savage or a 6.5 wildcat version would be a even better round. a medium loaded 260 remington would blow the doors off the 6.8 SPC or the 6.5 grendal. there are a few threads on the 6.8 in the calibure conversion area here. Im not trying to poo poo the idea it just the 6.8 isint being very well supported lately. I think remington stoped making guns for it. now there trying to pedal there 30 RAR or what ever the hell there calling this years wonder round from them. The 30 RAR in 6.8 or 6.5
would be better also and fit the AR mag well.

What's needed is a flater shooting, round than the x39 and has the "thump" of the 7.62 x 39 or even a bit more. Reliability is the action of the rifle. Caliber would be nice to have compact rounds, easily carried, and easy to keep firing even after many many rounds in a fire fight. I think that even the .243 Winchester would be a helluva round in combat situations given the right rifle and the right conditions. Personally, I think any rifle that jams and fails as much as the M4 does, NEEDS replacing, and immediately. If you're going to replace it, then put something in the hands that's accurate, hits hard and easy to pack around.

300 FPS is a lot. add 300fps to the 7.62x39 and your in the 300 savage range and nocking on the door of the 308 Win.

the 30 RAR or what ever remington s calling there latest wonder round would come close to doing that but at a reduced mag capacity. the 243 would work or the bigger brother the 260 remington. the 260 would be good for well over 600 yards. the 6.5 credmore is another one. The reason we have all these short rounds is the mag size of the ar nad the Ak. why not build a light weight gun that has a little more mag length Like a 10 but with out the weight.

im sure ammo weight and recoil and how fast it heats up the gun ect are all factors. running a hot .30 round through light barrel is going to over heat faster.

Personally if i had the choice of firearm to take to the sandbox, a 1biggun worked AK in x39 would be my number one.

the stuff Im rebarreling is way to tight in the chamber for any combat use. some better ammo over there might be of benifet and a better sight or optic. but I wonder if those guys ever aim anyway.

Im not really doing any thing that special to my stanard 7.6x39 builds other than the trigger and adding a scope and loading my own ammo.

I dont think my triggers would be very good if I was waking around in battel there way to touchy. a better two stage trigger might work. I hope I dont ever have to find out in a battle.

Im not sure what has more energy at 200 yards a 6.8 spc or the 7.62x39?? I think the 6.8 would be better than the 223 at any rate on people.

Reliability is the action of the rifle.

not nessacarly one of the reasons the AK47 is so reliable is ammo. the x39 has a lot of taper that aids feeding. if it was a straighter wall case it might not be as good. I do agree the action is more reliable. it is slightly over gassed and there is pleanty of carrier travel to allow that with out problems. My 2223 will get a stuck round every now and then when dirty the x39,s Havent had that problem.

I dont think the 6.8 SPC is a bad round and the second version with the bettter twist rate and closer to the advertised speeds then the first version was. I just think a 6.5 round will do everyting as good or good enough but have a extra 100 yards of usefullness and accuracy

Yeah not to repeat older threads but the rule of thumb I've gone by is 6.8 = .308 performance out to 400 yards in a .223 sized package; 6.5 Grendel = long distance performance.
