Semi auto MP5K Answered

Picture of

Hello everyone, i am back agian, with something non generic. I've seen to many basic "slide action" and simple "pin-pull back" guns. Usually, replicas that look good, often can't shoot, and most ugly-looking guns have a unique mech. I decided to combine the two, and make a decent looking mp5k, with a semi auto mech. The mech is different from my semi auto vector's mech, because the trigger is much more stronger than before, and never breaks. This is an unfinished gun, so will post instructions later. Pros and cons:

-semi auto, original idea
-magazine with internal pusher
-super good looks (compared to my airsoft MP5K)
-I kinda perfected the front sight
-excels in CQB in knex wars (if you are going to have one)

-hard to pull the trigger
-shoots below 20-15 feet
-a lot of cut pieces
-cut pieces are needed (unfortunately) sorry guys ;(
