i have 2 question that have bothered me for some time now. finally i have finished my nova 1911 sfa build. and it shoots great, the only problem is that it only shoots around 300ish fps with standard mags and 310-ish with a mag that i installed KM hi flow valve. parts that might effect fps is as follow:
prog4 BBU
shooters design POM nozzle
firefly floating valve
firefly soft hop rubber
PDI 6,01 inner (standard, not raven or palsonite)
one mag with KM hi flow valve
guarder "blue can" gas
i dont see any gas bursting from the ejection port or from the back when i shoot, i dont feel anything "strange" with the way the gun handles, but the chrono results is kinda low IMO.
what do u guys think? and oh , everything else is nova and prog 4, but i dont think other parts effect fps so i dont list them all.
one more thing,the parts that bumps hard/ receive the biggest strain during blowback is the spring plug hitting the back of the spring guide,transferring the force to hop unit and slide lock pin right? soo the harder the blowback the more stress those parts is under right?
what part/parts receive the most stress when the slide moves back to battery? eg:if i use a relatively hard return spring. i know the lug inside my hi capa slide get damage really bad by hitting into the back of an SD chamber to push the "chamber+outer" assy back into battery. but what if i use prog4/IK non tilting chamber+outer? will that lug still hit the chamber? without that lug (lug heavily damaged) all i can think off is the one that stops the slide when returning to battery is the nozzle hitting the hop unit/hop rubber? anyone can enlighten me with this?
thanks
