I am getting a Beeman RS2 when I return from Afghanistan. I will be in Maine where is gets pretty cold but would still like to be able to shoot. I hear the Gas Springs do not suffer from the effects of the cold like wire springs do. I like the duel caliber option of the RS2 which is why I am getting it. A gas spring would make this a good multipurpose all weather rifle. Would the "Red" spring give it the same or perhaps a slight bump in power as well? I know you do not recommend the "yellow" but I would also like to get a slight to moderate increase in power if possible.
I am told the RS2 spring is a .120 wire dia - 11" free length with 44 coils - inside dia .465 outside dia .715. Would the Gas coversion maintain at least equal power if not increase it a bit? I am guessing the gas conversion will make it smoother as well and more accurate.
Where can I buy a red piston for the RS2? Do you do the conversions? If so what would you charge?

I don't do conversions for others but I think mikeiniawoa does them. I believe he is at Flying Dragon Air Rifles - 515-924-3699If you do it yourself, you need to measure the exact stroke length of your rifle before you order a gas spring. I gave some sources at the beginning of the thread but you need to know what to order first.
...So far I'm preferring to use the N-Forcer products. It seems to be a smaller company that is willing to deal directly with end users. Just deal with them in a professional manner and it should go fine. They cost about $45+/- for the airgun sizes and they give a small discount for ordering 10+ of any one item....
Which one of those gas springs could I use for my B3-1's? My B3's are the old ones, with the white spring guide.
I tested a red label gas spring in my TF99 this week. Even after shortening the stroke a little bit, it still produced about the same velocity as the stock spring. 720fps with CP 14.3gr. The stock spring in the TF99 was unusually long with a lot of preload.
