Hello, I have managed to get my hands on a great VFC m4 which is a smiling size to an mp5 so I plan to use it more as an smg but also if I want to field it in woodland games that would be great.
The barrel I have to use is a 147mm 6.03 bore.
Can anybody help in what will help me achieve 350fps? Any tips etc.
What cylinder do you recommend? Should I go for a full cylinder or a 1/2. Etc
Thanks
