This gun took me a long time to get right. First was the issue of the mech, which turned out really complicated, then the issue of a good magazine/ammo, then the issue of making a good pin guide for two ram rods, and finally, I had a lot of firing inconsistency which took a while to nail down. (it shoots good every time now!)
Let's see some pros/cons, shall we?
-Fires two shots at the same time
-Looks quite awesome
-Comfy (even distribution of weight)
-Has awesome red dot sight (modded from knexpete's)
-Has two ram-rods
-Has a sturdy pin guide
-Large mag capacity -->18 rounds (9 shots) (mag can be extended too!!!)
-Can hold many rubberbands
-Awesome range - 30-60 feet (30= ~1 band, 60 = ~4-5 bands)
-Removable and preloadable double mag with internal pusher (modded from Knex.X's)
-Epic pullback length
-Uses the awesome handle from my ASR v1!!
-Very piece consuming (it's 9 layers thick...)
-Uses a few cut pieces (but don't all guns use 'em nowadays?)
So that's about it for this gun. I'm very proud of it and how it turned out. (my best gun so far (imo))
