    Yeah we discussed this a while back. I think it would be a good conversion, probably easiest to convert a Saiga .223 rifle or something similar. .223 mags should work but it probably needs a new follower.

    Id go with a 6.5 grendal instead.

    I have a 6.8 spc barrel but the round just dosent excite me. Id start with a 223 kit or sagia with spring loaded firing pin and open the bolt up. a 223 ak to ar mag converter would allow you to use the 6.8 spc specific mags. its certainl doable.

    there are now two versions of the 6.8 spc the version two its the one to have as it allows higher performance. the twist is differant as well.

    I'll have to read up on v 2 as I thought that was for a chamber improvement that wasn't made to the first batch of barrels.

    The reason for 6.8 is that you get .308-level performance out to 400 yards in a .223 sized package. Nothing more. A 6.5 Grendel / 6.5 PPC is for long-range accuracy in a .223 package. The whole "no one can use our reamers but us" thing with AA has really turned me off to the 6.5 Grendel altogether.

    reamers that are very close to the original are avaliabel for rent. they work well I did a barrel for a vz 58 that came out good.

    your get 308 trajectory out of a 6.8 but you dont get the performance of a 150GR 30cal upon impact.

    the 6.8 has never performed as remington advertised

    If ya want a 6.5 grendel you can use a 6.5 bpc reamer. Thats what I rented for ibiggun when he did the barrel for my vz-58. What he did for me worked awesome. I agree with ya on what AA has been doing. The grendel would have really taken off if A.A. would have allowed it to. Personally I like it much better than the 6.8 spc . Comparing the two AR uppers I have, the grendel is much more accurate and that's using wolf ammo.

    Not to drift, but I think Les Baer Custom, Inc. released the .264 LBC-AR so maybe the Grendel reamer thing will loosen up a bit.

    I saw that and it appears,if I read it right, that the specs over lap and it would work with grendel ammo. Probably their way of getting around A.A. fees.

    In my limited reading, that's how I saw it.

    theres there is more than a hand full of reamers out there that will shoot the grendal round the 6.5 green doll is one. not to take away from alexander armsas he is the one to bring the round to market but he didnt do anything that wildcaters have been doing since day one. he took a wildcat (6mm PPC) of a wild cat (220 russan) and wilded cated it by blowing the shoulder forward and expanding the neck. there were already 6.5mm PPC and variants out there. He did a lot with the round but also killed it by trying to hold onto the rights to be the only one to make the chamber. The easy way to go around that is do exactly what he did Wildcat his wildcat. add a thou to the length change the neck dia slightly or the neck angle a degree and order a reamer. There are nemerious improved versions of the grendal out there.

    If i want a 6.5mm rifle tht does every thing that the grendal does but better on a AK plate form ill just build a 260 remington, OH WAIT I ALREADY AM. If I want to buid a close version to a 6.8 spc that will far excede it ill just build a 7mm-08 OH WAIT I ALREADY AM. its pretty simple to get a 308 length round into a standard AK reciver why keep trying to get more from a small round when a bigger better cheaper version will work. the grendal and 6.8spc both run higher pressures than the 7.62x39 BTW. Your going to haave to mod a reciver and do custom stuff might as well just make it take a 308win length round while your at it. grendal and spc ammo is not cheap so your going to want to reload any way to feed it might as well just reduce loads slightly on a 22-250,243,260, 7mm-08, 308, 338-08, 358-08, etc to get what you want and use cheaper avaliable brass. oh yea there is a 6.8-308 / 270-308 wild cat out there as well nobody really uses it much because the 6.5mm and 7mm bullets are better and more choices.
