Point being? Take a stock TM M14, put in metal bushings, Prometheus airseal nozzle, and an MS110 spring and you have a stupid accurate 420fps sniper rifle and thats without a tightbore.
Any gun can be upgraded to the tits, I'll take a TM ver.7 mechbox over some G&G/CA frankenbox anyday. Every single part in a TM M14 you can get replacements for either original or aftermarket, can you say the same about CA or G&G? They have too many proprietary parts that aftermarket parts manufacturers wont touch and the original manufacturers wont sell separately.
