This is something I discovered and wanted to share. Might not be a big deal for some, but, the change affected my cheek weld and scope height enough on my M3 that I thought others needed to know.
First off I really like the one piece design that allows perfect (subjective) alignment to all the lowers that connect to it. Added stiffness and a change in harmonics are bound to be positive.
I received my 30MOA "short" in black for the M3 and if I liked it I would get another one for the MKII. I have my scopes mounted in Eagle Vision quick release ring to quickly mount them on either gun. With a caliber adjustment in Strelok I'm ready to go.
Well, I popped my scope on the new AirMarksman M3 and went out to make adjustments due to the new "30 MOA" I realized I couldn't get a proper cheek weld to find the eyebox @10x. My neck was all torqued to an uncomfortable position. This change all due to a bit more than a 1/4" cheek height loss from the thicker rear part of the backbone. I can obviously raise my scope up a 1/4" with the adjustable rings, but that's not the point. The new AirMarksman rail added 1/8" to my scope to bore height, which is 3.25". To add another 1/4" is, well, another 1/4" in the wrong direction. This might be nit-picky, but sometimes small details can have a big impact, especially on my neck. I can also fabricate a new replacement cheek piece that is 6.63mm (1/4") slimmer than the stock piece @10mm to get my 1/4" back. This is not necessarily "plug and go" for everyone, as some upgrades can be challenging.
Again, I just wanted to share the differences between stock and the new AirMarksman for those who can make the necessary modifications and for those who can't.
I am satisfied and will buy another for the MKII.
Here are some photo measurements.
