I'm building a Vietnam era retro AR.
I have gotten far enough with the A2 lower I started with:
Now I need to work on the buffer tube attachment and need reliable dimensions taken from either an original Vietnam era A1 lower receiver or one of Nodak Spud's Retro lowers.
Please see these illustrations for the measurements I need:
To make it easier on those who would help me, I thought I'd provide the following. Just copy, paste and fill in:
A (HEIGHT of tab at top of buffer tube attachment ring) = [ ]
A2 (THICKNESS of tab at top of buffer tube attachment ring) = [ ]
B (HEIGHT of buffer tube attachment ring reinforcement - measured from top of rear take down pin detent housing to where it is tangent with OD of buffer tube attachment ring) = [ ]
C (WIDTH of buffer tube attachment ring reinforcement) = [ ]
D (HEIGHT of rearward continuation of receiver side surface - measured from top of rear take down pin detent housing to where buffer tube attachment ring meets surface of receiver side) = [ ]
E (WIDTH of tab at top of buffer tube attachment ring) = [ ]
F (THICKNESS of buffer tube attachment ring)
- (measured at 3 & 9 o'clock) = [ ]
- (measured at 5 & 7 o'clock) = [ ]
G (outer diameter of buffer tube attachment ring, measured at 3 & 9 o'clock) = [ ]
