thanh Posted April 27, 2019 Share Posted April 27, 2019 https://www.patrolbase.co.uk/specna-arms-sa-e12-edge-carbine?fv=9283 The specification said it was 310fps. I'm new to the sport and this is my gun, does this mean patrol base has an m90 spring inside my gun as the fps I would like is 330. Was wondering what spring I would need to get to 320 to 330 nothing above that fps. Also should I contact them unless this is suppose to happen.

Nick G Posted April 27, 2019 Share Posted April 27, 2019 Specs quote 310 fps plus or minus 10 % Your 291 is well within that 10 % Springs vary , an M100 based on a multiplier of 3.3 to convert from M/s to fps should give you 330. However I have an M95 spring in my L119 build and its in the 340's. How well the gun is sealed will affect your output, air leaks in the piston or hop will drop the figure. TBH 291 is an ok figure, get your hop set up well and you will be getting plenty of range. That said its quite easy to change the spring in one of those so if you do want to push it up it doesn't involve stripping the gun so you could try an M100 to see where you end up.

Supporters Druid799 Posted April 27, 2019 Supporters Share Posted April 27, 2019 Ignoring the FPS , what’s the range and accuracy like ? If there acceptable (be realistic) then you don’t need to change anything. Link to comment Share on other sites More sharing options...
Supporters Rogerborg Posted April 28, 2019 Supporters Share Posted April 28, 2019 As above (qualified). These are expensive toys, not pieces of quality engineering. The smallest air leak or a fraction of mm gap between your nozzle and bucking can reduce the energy output. Conversely, as a toy gun beds in, the energy can increase - my G36 went from a disappointing 280 up to 330 just through use. Yours might not though. As to ignoring the fps/energy, the BBs don't care about airsoft magical thinking. They will go as far as their linear velocity (speed, direction) and angular velocity (backspin) dictate. Given the cost of springs, and that you've got a quick change system, I'd go ahead and buy an M105 or even M110, sling them in there and see what happens. You can lop a coil or two off the end to reduce the energy a bit: after cutting, heat the last coils with a lighter and flatten them out again. Be aware this might reduce your RoF or semi auto response: damn physics again. Link to comment Share on other sites More sharing options...

Steveocee Posted April 29, 2019 Share Posted April 29, 2019 Don't lose sweat over a few FPS. It's so easy to buy into the FPS race to the top but it's rarely worth the effort. Link to comment Share on other sites More sharing options...
Asomodai Posted April 29, 2019 Share Posted April 29, 2019 Have you adjusted the hop? Adjusting the hop to increase the effect/range will result in less FPS. Link to comment Share on other sites More sharing options...
RonLancs Posted April 15, 2020 Share Posted April 15, 2020 Just received a SA - E12 and I’m disappointed. Not yet fired it but already the build quality is poor. Wobbly trigger guard, crisp packet mock bolt cover and the dust cover won’t stay shut! - Nuprol has better build quality - NUPROL. I am disappointed and depending on how it shoots is going to determine if I keep it or send it on back. Link to comment Share on other sites More sharing options...

Id send it straight back, otherwise PB will find a way to wiggle out of it Link to comment Share on other sites More sharing options...
RonLancs Posted April 15, 2020 Share Posted April 15, 2020 Send it back for another one or choose a different weapon. Tempted to just wait it out and get a budget of like 400. Just wanted a little CQB’r but I just cant ignore these little things - 179£ at the end of the day. Cant believe my Nuprol Delta is better quality!!
