spyders are awsome, the only thing i dont like is they are startin to put lil anoyin drops on stock, the barrels and bolts can be bad,
my xtra has everything stock exept java bottomline (gets rid of fore grip, and drop) , a spyder se x chamber(green&bacl splash anno
) that i need macroline for, and barrel,sight rail/bevertail, lpc, and grip pannels from the sonix
and a slight ly modded and heavaly filed trigger, it looks almost like the new viking trigger but a lil thicker
and it fek!n rocks!
and they are very cheap and reliable stock
