stock timmy bolt, stock fits better but isnt delrin or anythin special i dont think so this gets a little bit better efficiency but nothing huge.
very sexy purple to black faded 2k2 with evil hammer and evil bolt, delrin piston for lpr, stock torpedo
Delrin so it's decently light.
Multi holed head.
Tight fit into body. (use lube to keep good movement and consistency)
I like evil stuff usually but this seemed to be a tight fit into the body, i mean it works fine but unless i use some slick honey lube or somethin it just feels like it is too widely cut or somethin. Other than that it seems fine, no huge efficiency diference either way so its tuff to say on that front but a bolt can only do so much anyway
My timmy upgrade bolt experience is somewhat limited so im gonna have to say if u like evil's stuff it definatly works fine, but i wouldn't be surprised if other upgrade bolts offer better efficiency without the tight-fit-ness.
