Project Information

80%/76% Builds:

  • Our 80% build kits come with small pockets of material left over in order to qualify as unfinished firearms, thus allowing us to deliver you this service. 

  • The pockets of material in question are made from the same material as the lower designed similarly to support material and is  to be removed by the customer and are located in red in the following images below.

If you have completed an 80%/76% build before this will be nothing new for you, only made simpler due to the slightly weaker material we use as compared to polymer injection molding. Similarly we also use the same tool set to complete these lower receivers namely a drill press (or hand drill), vice etc. However due to being printed lowers in terms of rail specification you must search in the description of the respective design where you will find the rail type for you to source. Additionally you will need to source the following list to complete assembly: 

​​

  1. Lower parts kit 

  2. Complete slide assembly 

  3. Magazine

  4. Front & Rear Rail set (FMDA DD26.2,PY2A, SS80, P80) 

  5. Locking block (FMDA 26.2,PY2A,SS80,P P80 & OEM also works)
