About this 3D model

I made this scope for my son to use with his gigantic arsenal. It fits most guns but i found that on some of the older guns its very loose. I print the gun verticaly to mininize supports. But they are required. I used super glue to conect the bracket to the scope and the 2 barrels together. you could also make a reticle with clear plastic and insert between the 2 barrel sections
