Absolutely love everything about it. Action is super smooth, 60 degree is so efficient and quick and surprisingly easy to lift.
Switching barrels between the 6GT and 223 has been quick and very repeatable. Point of impact has been the same or better than my desert tech when switching barrels which blew my mind. Most of the time it’s only 0.1mil high on the first shot and then after that it’s almost always back to a perfect zero. I am not torquing the barrel and just hand tightening it.
I switch barrels quite often and even remove barrels when cleaning.
I do have a 1.1mil change in elevation when switching from 6Gt to 223 but I do not expect it to be the same and it’s easy to zero my scope. I never saw more than 0.5mil difference in my desert tech when changing from 338LM, 6.5CM and 223.
Joel Russo is an awesome knowledgeable guy and has always answered the phone every time I have called and even helped me with other shooting related issues not related to his product.
I should add: never had a single issue feeding or extracting with either the 6GT or 223 when I got the mag block installed in the MPA chassis.
