3D model description

Hello all, Here is a custom design Ive worked on for a AR lower receiver for you to play with. It will accept mil spec parts with little modification based on what material you use and the shrinkage rate of such. It requires a side charging upper. Included in the download is the bolt catch cover and buffer tower brace files as well. Also included is a 9MM adapter for glock style magazines. Like always this is a model and the end printer should check with all laws in your region about printing things of this nature. be responsible, be safe, and be smart.

end user accepts all responsibility for printing this.

3D printing settings

its your choice of material but Carbon fiber, or nylon should be strong enough for pla printing.

If resin printing I suggest 50/50 mix of Monocure flex 100 and elegoo black (13 sec's per layer or 50/50 siraya tech tenacious and elegoo black 8 secs a layer. Cure for 10 mins in your UV chamber and then let air dry in a UV free environment for 3 days prior to assembly.
