Can someone tell me how do you go about mounting the M93A on an AR so it meets legal regs? Does the stock come pre-pinned or do you pin it in place/position yourself? Excuse my ignorance..newbie here!

You can special order it directly from MagPul pinned in the position you want. You can also send in an M93 or M93A that you currently own for it to be fixed.

I'm not sure if any other dealers offer this service, I ordered mine directly from MagPul.

Here is mine fixed in position four, mounted on my Colt MT6400C:



After the sunset MagPul will restore your stock to it's proper configuration

Edited to add: Oops, Troy beat me to it.

Sweet lookin rifle Cjan!!! OK will get it direct from Magpul

Thanks

Good luck with your new MagPul-they are worth every single penny even when fixed. With the exception of the Crane, I own or have tried nearly every type of fixed and sliding buttstock on the market. The MagPul is the most comfortable I have ever had the pleasure of installing.
