I recently came across an aftermarket barrel made by ARP for a Savage bolt rifle in 6.8SPC. Nobody makes a bolt gun in that caliber and ARP made a limited run of barrels recently. ARP makes a lot of barrels for the AR15, mostly in 6.8. I have 3 of them and they’re great shooters. I missed out, but acquired it from someone who had one and couldn’t find a good donor that he liked. Savage was making the 110 Prairie Hunter in .224, but they’ve become nonexistent. The .224 uses the same case as a 6.8, but it’s a longer round.
I ended up picking up a Savage 110 Tactical in .308. It comes with an AICS mag. In order to make it work, I have an 18” 3R/11.25 melonite treated barrel. I also ordered another bolt head from PTG in 6.8, a new barrel nut from NSS, and a new AICS MDT mag in .224, because of course nobody makes an AICS mag in 6.8.
To modify the mag, I got a piece of high density plastic and was able to trim it down to .30” and fit it in front of the mag, since it’s a shorter round than the .224. I also had to trim down the follower a little bit.
The bolt head and nut should be here next week. I’ll post some more pics once I start tearing it apart.
