Mrod internal regulator

[Erevojoe]

A few months back someone had put ups I Link to a regulator when I had asked how mods regulate air pressure inside of them.  I can't seem to find it anywhere and I've been in touch with the guy from airgun importer and he doesn't make his anymore.  Does anyone have a link to a commercially available regulator that will drop into a 25 cal mrod without a lot of modification?  Ive seen many posts where they say it isn't important but if tuned well, however I, understanding how pneumatics work So I'd still like to give it a shot if you don't have to modify too much.

hey-Hey!!!,
There is no drop in I know of. The issue being a 25 cal's plenum size requirement; you need a substantial volume between regulator and valve and there is the rub. Since the reg has to be so big, you lose un-reg'd volume on a level that leaves the rifle better off un-reg'd...IFF you can shoot the FTT at around 30 FPE, you can get away with a modified gage block, a short spacer and a small hole to vent the reg.
