Any one use a barrel nut system for AI barrel changes? PVA has them to upgrade the older AI models. Can use the Barloc also. Seems easier than taking the chassis apart.
 
Well, every one must have all the latest AI's. Still love mine. Going to do a barrel change soon. I might have to buy the barrel nut and Barloc, and see how it works.
 
ATY's have a screw on the action to take them apart. There is no screw on the AE. You have to take the barrel and put it in a vice and use a wrench to remove the barrel.
 
Even with a barrel nut or barloc setup, you'll have to loosen the action screws or remove the action from the stock during a barrel change anyways because the front action screw on an AE is in the recoil lug and not in the action. Things are going to move around if you loosen the barrel without loosening the action screws first as the action and rear action screw will no longer be attached to the recoil lug and front action screw. It's not like a Remington where both action screws go into the receiver.

Also, with the front action screw being in the recoil lug, proper barrel torque is going to be important to keep the recoil lug securely sandwiched in place to keep things from moving around under recoil.

While I sold them both a while ago, both my AE Mk3's were within the normal AI dimensional specs for prefits, so barrels were easy to find. Some AEs have a bit more dimensional variation from the recoil lug face to bolt face than AW/AT/ATX/AXMC's because of additional tolerance stacking with the recoil lug.

I was aware of that. I just figured most people would prefer a shouldered prefit over a barrel nut.

This part makes sense. I have re-barreled two ae rifles with at barrels and did not have any issues. Screwed them on and torqued them. Checked headspace and both were good to go.
