TM FN-57

Thinking about getting one of these but saw they run 230fps on 134a(144a) gas but around 280fps on green. Are these okay to use long term on green gas as i heard it cracks the air seals on tm pistols ? Also where can you get mags for them ?, I know they are quite scarce

use abbey predator ultra gas,i know plenty of people who have used green gas in tms all year round and been fine,as long as you do a regular maintenance on seals with silicone grease,you can get mags ai pro airsoft supplies and wolf armouries

Airsoft world also do magazines, I use abbey predator also and have had no problems with performance.
