does anybody know of a more accurate fps rating to the guarder sp110 spring??

blueballz · June 2nd, 2006, 19:37

hi everybody..quick question..esp. to ppl that owns/owned the guarder sp110. whats that spring suppose to bring my fps to??? i have searched soooo many forums and websites/stores...and have gotten totally diff. answers. it ranges from 360 all the way up to like 425 or sumthing.i know it varies from what other mods i have done to my gun but i have a tm commando m733 got metal bushings, systema poly pistonhead, and the guarder 110 everything else is stock...oh and a 9.6v battery and it chonoed at only 362 fps. so im now debating if i got a lemon spring?? and now im thinkin of getting the sp120 but im not sure if thats gonna bring my fps to like 440! and that would ruin my internals.

please help.. thanks !

360 would be average if you didn't have any bearings on the piston head or the spring guide. My gun is heavily upgraded; I get 410 with a SP120. In your bearingless small carbine setup, you would get somewhere in the 385 area. Keep in mind that FPS is determine by so many variables. Ultimately it boils down to one thing = airseal. Good luck. I'm sure someone will reply and have another answer. That's the thing with airsoft -every gun is different.

1 meters = 3.2808399 feet
so the SP110 stands for 110 meters per second
or exactly 360.892389
so if your spring is a lemon, then my head is a coconut. That spring is shooting EXACTLY the fps it should be.

the reason we tend to recommend the 110 these days is to give room for other upgrades.
the SP120 should land you right at 394fps...but if you get a better piston head, or a tightbore, it could push you over 400fps.

so at 360fps, it gives you safe room to add other upgrades without going over 400fps.

Piston head or tightbore wouldn't do all that much for fps, but a spring guide with thrust bearing increases fps

Trader rating · June 2nd, 2006, 23:17

a piston head with a bearing can add fps the same was a bearing spring guide can. A tightbore can add a few, but not as much as some people think.

I tested a Guarder SP110 on one of my M733 before and it was shooting 415fps. My set up was. TM ported piston head, spring guide w/bearing, airseal nozzle and 6.03mm tightbore innerbarrel. And yes I also tested a SP120 spring with the same set up and it was shooting 425fps. my two cents!

blueballz · June 2nd, 2006, 23:39

thanks for everybodys input. i feel a lot better now that i know my spring isnt a faulty one. but i do have a piston head with bearings. the exact things i have on my gun is the duracon pistonhead w/bearings, guarder dual oil channel steel bushings, and the sp110. do you guys think if i installed the sp120, and add nuthin else to my gun, would it hurt the internals?

on Sp110 you'll be alright but if you will be using the sp120 make sure you change your gears to reinforced. I already stripped a stock TM spur gear on one of my AEG.

blueballz · June 2nd, 2006, 23:53

damage- you stripped the gears with the sp120? hmm...do you think its becus when using the sp120 you were shooting at 425 and thats what messed up ur gear. cus in my situation, i think the sp120 will jus jump my fps to 395-400. i was told that id be ok as long as my gun shoot 400 and under. but then again , there can be an airleak somewhere so thats why my gun is shooting weak. so maybe the 120 might ruin my gun without me knowing it....any opinions anyone before i do the spring change...thanks

Actually yes you can use SP120 but it will lessen the life of your gears if it is stock.

Ghillie973 · June 3rd, 2006, 00:11

Not sure if you've already done it but you might want to replace your spring guide with a stronger one.

blueballz · June 3rd, 2006, 01:20

no i havent, whats a spring guide for ...i was told that i dont needa replace that unless my gun shoots harder than 400fps

Mantelope · June 3rd, 2006, 01:21

I've got an SP100 shooting 398FPS in my CA33E. Don't know what an SP110 would do, but I can tell you it'd be a crapload more.

Actually the bearing on the back of a piston head is not as thick as the 'block' a stock TM piston has on the back of it's head (for the head to screw into and to hold the stock spring), so the bearing wouldn't increase the fps at all, will just reduce any effect the spring torquing would have on the performance.

Tightbore adds at the most 10fps, mainly due to less air leaking past the BB as it travels down the barrel.

I've got a Prometheus 110SP spring in my MP5 now, a quick game chrony with hop up set for 0.25g and that ammo, got me 325fps. I used to have the PDI 150% in (a GOOD one) and it netted me 370 with 0.2g, no hop up, and with hop up 365fps. With 0.25g I think I'd get mid 330fps, so I think my 110 spring is a bit lower than the PDI 150% I had in there.

So, I'm guessing my 110SP and bearing spring guide are giving me about 350-360fps, lower than I'd hoped I'd get.

I've been running an sp110 for the last two plus years in my M4. The only other upgrades done to this rifle were Guarder bushings and a Guarder nozzle.
This rifle has chronoed at 399 and 400 fps consistantly for over two years.\

EDIT: this is in an otherwise stock TM mechbox, using a Systema hop up unit and a stock TM barrel.
