Thanks for the response. I appreciate it

So i have two questions that i cant get Mr. Derwood to answer.
1...is the trigger group that of an AR or a glock 17...my assumption is Ar15...
2... buffer spring group...is a 15lb flat style spring going to work for primary spring.
Thank you for your time and for your stl files.

AR trigger group and the primary spring is a standard ar buffer spring. The smaller spring is the more difficult one to source. I used the spring number from his directions and searched until I finally found one online and even then it had to be cut down.
