Have a look in the retailers section and you will find good reviews of Taiwan gun, including mine, they are my goto RIF seller. As a retailer they are great, and they will do downgrades/upgrades for the cost of the part (specifically spring changes), and include a sheet of fps tests using .2 ammo. They also answer e:mails quickly and in English and my last order of about £300 of stuff came with some free goodies as well. However YOU must make sure you have a skirmish defence or customs will seize your rif, and they won't 2 tone.
