No longer confined to small groups, I need an upgrade from my gas beretta. It's been suggested I get an TM AK and get it to 450fps, but I am unsure how costly this is, and the cheapest US retailer I've been referred to is KastwayAirsoft.
-If I get a stronger motor that is/is similar to a TM EG1000S, will the gears be able to take an M130 or M140 spring for more than three months use? (fps limit is 500)
-How much of a difference does a tightbore barrel make for accuracy and fps?
-Are there any other local repair shops in the Phoenix area and surrounding areas besides Jungle Toy and Softair Depot? How long are the wait times?
-In general for a $400 budget, what are things I should get for a TM AK-47?
