scrub 0 Posted August 30, 2013 Report Share Posted August 30, 2013 Hello,does the Vepr 12 self regulate gas cycling pressure?Is the design one in which they have come to a compromise of the size of the gasports required to cycle a variety of different shell loads?AS opposed to the Saiga 12 which has the adjustable gas plug to vary pressure dependent on load size,thanks for any info,tom Quote Link to post Share on other sites
ec4321 113 Posted August 30, 2013 Report Share Posted August 30, 2013 It doesn't regulate, IMO. Seems like fancy marketing. One setting to solve all issues. High Pressure. Quote Link to post Share on other sites
thebuns1 4,323 Posted August 30, 2013 Report Share Posted August 30, 2013 Im no engineer, but I havent been able to find anything that would obviously make it self regulating, but Im not going to say it isnt with 100% certainty. Im not sure of why the design difference in the puc/piston, so its hard to say. Quote Link to post Share on other sites
poolingmyignorance 2,191 Posted August 30, 2013 Report Share Posted August 30, 2013 They have 5 ports and from what I can best figure is the piston is delayed from reciprocating by binding inside the hollow of the puck, due to the loose toleranceof the carrier tilting during cycling. This is the only thing i can think of would make then claim "self regulating". My guess is that heavier loads accelerating faster create a greater tilt and increase contact time of the piston in the hollow. I could be wrong. Quote Link to post Share on other sites
scrub 0 Posted August 31, 2013 Author Report Share Posted August 31, 2013 i noticed in some of the pictures Papa zorro has posted of what I believe are comp guns there appears to be an adjuster on the front gas block like a saiga. Any ideas on this? Quote Link to post Share on other sites
ec4321 113 Posted August 31, 2013 Report Share Posted August 31, 2013 I think some said that was simple a removable plug on the front that made it easier to clean. Quote Link to post Share on other sites
thebuns1 4,323 Posted September 1, 2013 Report Share Posted September 1, 2013 For what its worth, I feel that it has to be somewhat self regulating. I dont really think its marketing bullshit, but rather that Molot wouldnt say it is if it wasnt. (somehow). Just because we cant figure it out dont really mean that it aint. Thats just my two dipshits. But like I said, Im not engineer. Quote Link to post Share on other sites
PapaZorro 401 Posted September 1, 2013 Report Share Posted September 1, 2013 (edited) GB you asking for is Molot IPSC GB modified from standard Molot FSB (similar to S12-030) work the same as original V12 FSB, it has the opening front for easy cleaning during competition (you don't need to remove Upper HG with Gas tube for removing gas puck and clean gas block), was designed for Vepr-12 VPO-206 IPSC model.
