Yep, the n00b sN1p3rz fad is one we'll either have to deal with or completely ignore. It wouldn't hurt to really do your homework just reading those KA-BAR threads. I don't mind trying to help people, so here we go.
This seems like a cool deal to me. KA-BAR loves his and my buddy has one.
(Well MB-02, short VSR)
With a bolt, it's not a bad idea to play stock for a while. Refining your skills is much more important than quick amazing upgrades (in my opinion). Being a "bolt turner" is a challenge, one of the stickies on here points that out. I think of it as something harder than normal AEG use. So I was glad to see your profile says you already have an M4.
I'm contemplating the endeavor myself. I once owned a pretty trick UTG L96. Now I sort of want a "scout rifle," something that's a little smaller, and basically a slightly more accurate and powerful gun that just doesn't require batteries or gas. It's kind of a fun adventure.
I've always been really interested in a Marui G-Spec (just keeping it stock), but the cost might turn you away. About $270 after shipping
here. It'd be cool just cuz you'd have a really soft-shooting, accurate, nice quality bolt that wasn't like what every other n00b owned.
Have a good time!
