3d Printable Luty SMG lower - Concept

grabcad

This is a concept I have been playing with after I saw a picture of a hybrid Luty on TFB (3rd Picture). This has not actually been printed by me. This is to show the simplicity of hybrid designs, I would suggest making the feed ramp out of metal but you could make a replaceable 3d printed ramp easily aswell. as for pins id use cheap rollpins there is not a whole lot of load on the receiver the sear is the only hole which might cause issues.As the Luty is hand made I cannot guarantee it will function with your Luty. In this model I use Either hunter1198 or M Bs model I forget which, but both grabcad users are worth your time to look at their models. I would also like to shout out M B again as he also has a hybrid design which incorporates a glock Maxgell which makes alot of sence as 3d printable glock mags are the norm for 9mm diy carbines these days.
