I'm dying to find out some more info & pics!
What's the width of the receiver? Length??? (It looks more compact than the original)
How did you do the bolt carrier mods & feed lever pin, & recoil springs???
The more I look at this one, the more ingenious ideas I see incorporated in this design!
You, Sir, have won the title of 'Homebuilder of the Year' for two years running now in my mind! SWEEEEEEEEET gun!!!
EDITED TO ADD:
Also, Does the Bolt Carrier modifications require you to use BOTH 'rails' created by using the shelving steel, or is the 2nd 'rail' part basically functionless?
