So, now that I've fallen in love with shooting my AR-15 this year, I was thinking about using it for deer season this fall. However, here in Minnesota 5.56mm isn't legal for big game; bullet diameter must be 6mm or higher. I've invested most of my fun money into reloading components, magazines, optics, etc, so high-priced (over $500) uppers are out.

Does the 6.8 SPC use the same bolt as the 5.56mm? If that were the case, I could just buy an SPC upper without a bolt and bolt carrier and use the one I have in my 5.56mm upper, right?

Both the 7.62x39, and 6.8SPC use a different bolt.


Get the 6.8SPC.

You have been BS'ed. They were probably talking about 6.5 Grendel, which is known to have such problems.

I tell you what , I will put a LIFETIME guaranty on any 6.8 bolt I sell. If you or anyone ever has lugs break, I will replace it at no charge to you.


You have to stop it, I Have 2 lowers sitting around. I think I might get into the 6.8 after the move. I told myself no more calibers, but i cant take it anymore.

6 months ago I sold my FAL because ammo was going up. I got 2 uppers in 7.62x39 for the price of ammo and availability and I am glad I did. I cannot get any Wolf 223 at the gun shows but plenty of 7,62. Tell your buddy to increase hammer tension on the springs. Both my uppers run 100% an my 16" runs 100% on Full Auto. Both shoot under 2" with Wolf Classic HP. Eddie

I've got a Ko-Tonics upper and love it. It sits AWESOMELY in my safe. I don't have a scope for it yet and haven't mated it to my DCM lower :( In other news, my credit card just took a hit from Larue Tactical on a Trijicon 2.5-10x56 scope with mount...

i was interested in one until he got his.

I guess I should go tell my bolt that he should have broken 4000 rounds ago. Are you sure your friend wasn't referring to 6.5Grendel bolts? Sorry, I was just thinking out loud.
