Hello. I have just started my +bow and have a question. Is one of the rear side plates suppossed to be bigger than the other, in length.
If by side plates you mean the 1/8" thick pieces that are screwed into the side of the gun, then there should be four of them total and there are two pairs of congruent pieces (pardon my geometry terminology).
The ones with the rail holes are identical and the ones with the + are identical.
There are a few changes to my first design here, and most of them can be seen here:
-Plate on the plunger rod extends to ride between the two stock rods -It's also rounded so it hurts less if by some chance you put an appendage in the way -Priming plate does the same -Rectangles attached to the side plates keep the arms from coming up when cocked
Lastly, it now has an adult-sized stock and grip:
I'm very happy with its performance and is as comfortable and useful as +bows can get.
