Ok I have a list here that I've been keeping of parts that I will definitly need for the .45ACP build, I just wanted to run it by everyone and see what they think before I go any further.
Green Mountain .45acp 20" Barrel blank
MAC-10 Grease Gun mag well
Romy G parts kit from CFS (for all the basic AK parts like dust cover, bolt,carrier,front trunnion, rear sight block, ect...)
Cetme or G3 triple frame front sight/gas block (in place of RPK GB)
G3 cocking tube with nonreciprocating charging handle
The one thing I do need is a RPK handguard retainer
The other thing I believe I will need is a custom made gas piston the same diameter as the piston head but the whole length of the piston, for use with the G3 nonreciprocating charging handle tube.
I believe all these parts will work and complete the .45acp build
Anyone who see's any problems or something that won't work or I forgot please let me know.
