This is the brass part of the breech.
Measurements
From end to end: 8 in
From (Green) end to edge of breech: 1.77 in
From edge of breech to edge of breech (lengthwise): 2.1 in
1 in around (as in diameter) was cut. Just a little more than half the pipe.
From front end of breech to front of pipe: 4.08 in
Here is a Pic of the fit of the dart; it's perfect.
(Get ready for lots of measurements in the next one. Its the pvc part)
Sorry, the pic doesn't completely show the other hole,
Measurments-
From end to end: 8 in
From back edge to back edge of breech: 1.68 in
From edge to edge of the breech: 2.44
From front edge of pipe to front edge of breech: 3.82 in
Breech Diameter measurement: about 5/8 in (needs to be sanded just a bit).
~IMPORTANT~ These next measurements are for the bigger hole that the breech arm slides through. I will refer to this hole as the "arm hole" or A.H.
From back of arm hole to back of Pipe: 1.23 in
From edge to edge of the arm hole: 4.45 in
From front edge of A.H. to front edge of breech: 2.25 in
A.H. Diameter Measurement 3/4 in
Ok, just so you know, I measured the decimal measurements with calipers, and the diamiter measurements with a tape measure. Thats why they are in fractions.
Lastly here is a group pic of all the pieces next to each other.
I really hope that this helps, If anything was confusing, just ask.
Edit: Also, I give full credit to FA24 for the ingenious breech design.
