Crosman 1377 shoulder support and optic holder

thingiverse

I'm sharing my tuning setup for the Crosman 1377 rifle, which I've thoroughly tested and optimized. The attached photo showcases everything fitted on it perfectly. The printouts are from PETG, ensuring a high-quality finish. This setup consists of three main components: 1) holders for 11mm optics 2) shoulder support 3) rear breech cap for shoulder support Everything is mounted directly onto the stock of the pistol, which remains unmodified. To replicate this setup, you'll need to acquire 10mm aluminium tubing from an RC model shop or hobby store. Additionally, four 3mm metric screws are required; if you prefer non-metric screws, simply drill a corresponding hole. To achieve optimal results, print each part with high-quality settings and 100% infill. This will ensure the parts are stable and the layers bond together securely. Post-printing assembly details can be found below.
