Sharing an MPA Chassis between two BA's

[Patty]

Anyone with experience or knowledge of swapping scoped BA's between one MPA chassis? Any issues with repeat-ability? Been thinking of using the MPA i have for my PRS rig for as platform for a vudoo V-22 BA. The V-22 will have its own optic that stays on the BA and the same for my TL3 in 6.5.

thanks!

as a test you could remove and reinstall your prs rig from the MPA a few times and see how that affects it (POI) if at all.

Only way to find out for sure and quantify it. Every machined dimension on a product has tolerances no matter how small. Most people don't have the skill or knowledge to theoretically predict how those dimensional stackups will affect a product so we are left with empirical testing.

If you leave the scope attached to the action and just pull the BA out of the stock then put it back in it stays zeroed. It's actually quite impressive.

I've had good results swapping a pair of actions out of an MPA chassis, both actions have their own scope so it's very easy. In/out of the chassis seems to hold zero. I'll see a zero shift if I'm moving the barreled action from my Manners to my MPA, but once it's zeroed to the MPA it's very repeatable.

Awesome, good to know! looks like i may go with the vudoo afterall then.

I used to do it all the time with a Stevens 200 and an inch pound torque wrench, consistent torque value is the key to repeatability.
