My question is about the M77 MKII reciever in that chassis.
If you look at the Scout series, Vs. a M77(MKII, Hawkeye) the floor of the reciever doesn't have "lips" on the scout. That way the magazines fit, whereas the Hawkeye needs them ground off. At least to work with the scout system.
Which mag system are you using, and did you have to grind off the lips??
...BTW, VERY nice looking!! I might hate you a little

I'm a firm believer in the theory that if it bleeds, I can kill it.
