View Full Version : Gas Piston

I am rebuilding a IMBEL kit from Dan's. I've shortend the business end to 16.25" not including muzzle thingy. Who makes the largest diameter (US Part) gas piston? Since the gas system will be so short I thought this was one way to prevent cycling problems.

hey nicco,
i like the dsa piston and metric tube(both new replacements). they are the tightest i have run across. when used together that is. at 16" you might need to make the gas port a little larger though. someone here once said it is better to have more gas than to worry about conservation of gas.
practicing conservation when you should be pursuing largess, i think were his exact words.
