There is no single answer for all the variations we encounter in a match. Sounds like your choices are very sound.

I would look at the lubricity of the two, oh, if the extensions need a bit of tweeking to match your individual mag for smooth feeding, I'll take Delrin every day.

Delrin is a very tough plastic. Maybe if you dropped a loaded mag from a 2nd story onto concrete, it may.

As someone that has used Delrin on parts for several decades, I will go with Taccom's extensions.

Differences in barrel harmonics. One of my AR's will shoot 55 Nosler Ballistic Tip 1 inch different in windage than Hornady 55 V Max bullets. Same powder and charge.

Yup, George shoots his Garand.

It's a blowback action. It's how they work.

Is your barrel ramped? I've been using Metalform or Brownell's 9MM mags (they are the same, the Brownell's are coated) and they just run. I do reload and have been for several decades. I guess I have a "feel" for the length of what will work. Try 1 or 2 of the Metalform or Brownell's mag. Don't spend a bunch of money on mags before you try a small sample of them.

The MOA lifter works! The owner had a hip replacement and it’s a small shop. You might have to wait a bit for the lifter or not.

That is good to know.

No Zero stop?

The lock is simply pull the turret up, then turn? Both friends had guns in racks when the "mishap" occurred.

I thought about this scope, I don't like uncapped turrets, not for a scope with a BDC reticle. There are a few "comedians" that play games. 2 friends that have run uncapped turrets have had their zero wander a hell of a lot.

I don't think it's just the barrel, but, the entire RDB system. I don't think it's reached it's full development yet.
