Yes, if you've seen one armalite, you've seen it all.. but heh, I love mine since I've placed more time/resources/effort into to her make it sturdy and perform well than my other 4 guns... So here goes:
TM M4A1 converted into a SR16.
- Slither stock replaced with full stock for suitment of large battery
- stock TM outter barrel replaced with CA M15 one piece outter barrel, completely solving barrel wobble
- stock TM plastic receivers replaced with G&P M4 SR16 metal body
- stock TM gearbox replaced with reinforced G&P gearbox w/one piece metal hop up
- Z-mount; reflex RDS, Walther tac light, Samurai laser
- internals are stock TM gears
- PDI 130% w/metal bushings
- inner barrel is M16A2 length w/TM SOCOM suppressor
- chronies in at 306 fps on 0.25
- shimmed and tuned by TKF's manchovie
I plan to add a integrated underail system later from Guarder, replace carry handle with a metal one, upgrade the spring to 150%, aluminum piston head, maybe helical gear sets as well. And, replace suppressor with a more suitable type. Oh, definitely get a better pistol grip, I can't stand this stock TM one!! Grrr!
