Hi, guys on the web there's is a types of buckings for vsr's, ones said gbb bucking rubber and others said only bucking rubber, the two of them are ver bucking but i don't know if there's is a difference between them, can I use a gbb bucking on a spring sniper?. Another thing, do you think if I design a piston complete madre of steel with a good slim shape con the back but a little more heavy on the front will produce more kinnetic power?

Jajaj yes, I'm from chile, and thanks again for your reply, well, in fact I have a E1 M28 and I have lots of ideas for it, I will be glad to share when is finish. About the bucking, the modify,, the only that i found is the tan color bucking, and the only review of that said that it wears fast, and for the 9ball, I have fear of buy it again. But!!, in the web of fire support I buy the PDI W-hold tipe bucking, and the lonex air seal vsr bucking, in other web I will buy the king arm air seal, and a SHS vsr 70degree red bucking, do you think they are ok?
