I received my AKT-E and put it in a Vepr tonight. I had hoped to get it out tomorrow to compare it with a AKT, but unfortunately it's going to require a lot of fitting and more time.
I had to put the roll pin in, then found that I'm going to have to file most of that pin down. I installed the trigger with the ALG High Energy Spring, and I'm going to have to tweak that too. Even with the Auxiliary Trigger Spring installed (supplied with the AKT-E to increase pull weight), I'd be surprised if the pull weight is much over a pound. And that's after moving the aux spring leg from the trigger wall to the mainspring leg. Without the aux spring, the hammer dropped by just touching the trigger. Tonight was a rare time when I wish I had a trigger pull gauge.
So no range report tomorrow for you guys as I had hoped. Hopefully soon.
