| Question / Issue |
| Has the barrel for the 6.8 upper always been SpecII or did it used to be SAAMI? Has the barrel always been 1:11 or did it used to be a different twist? Thanks |
| Answer / Solution |
Our 6.8 barrels used to have SAAMI chambers and 1/10 twist. They now all have Spec II with a 1/11 twist. If you see 1/11 on the barrel it has a Spec II chamber. |
