"Can’t say anything bad about it, it did its job.

"I am literally pulling 430 FPS with .30 on this matrix m130 spring with internal upgraded shs compression parts that I bought as a package off SINAIRSOFT on eBay. That’s 489 fps with .20 gram BBs. Dmr build on anything gun with a gearbox at this point. It’s in my sd6

"I stuck an M130 spring with an SHS compression kit and piston head and full metal rack piston with 18.1 gears and a matrix Godzilla motor high torque into the UMAREX MP5SD6 ELITE EDITION aeg and the gun was shooting 430 FPS WITH .30!!! And 489 with .20 BBs!! Only
Parts stock are the nozzle, tappet plate, and gearbox shell. These matrix springs paired with the right compression system can over shoot your gun making it reliable and high fps for outdoor play.

"Purchases an M115 for my Cyma p90 with approximately 380mm long 6.02 barrel. Chrono was just above 1.6 joules: 330-340 fps with a 0.32 BB. Was looking to get close to 1.5 joules for where I play so going to clip a few coils and see what happens. Surprised to say my stock motor and gears handled it fine even though it had more punch than expected, I do have upgraded cylinder and piston though. I was not able to play with the extra strength so have only fired a couple hundred shots at home with it.

"Dropped the 350-420 fps spring into a G3 and reliably saw 360fps on .25g

"It's just a spring, but easy to install in a Matrix Calico Jack.

"I put an M125 into my LCT RPK NV. It increased the FPS from ~410 stock (on an M120) to ~435 with 0.20g BBs. It's right below my field limit for 450fps, so perfect for my application.

"cheap spring with a wide rang of spring power....it gets the job done , what more can i say its a spring
by Stephen H. on 03/17/2020
"My go-to spring for upgrades and downgrades. Keeps me field legal in CQB and gives me the range I need out in the field. Just make sure your gearbox can handle the strong spring or it'll lock up. If it half-pulls or constantly requires several trigger pulls for a single shot, let the piston release and then get that spring out of there.

"Buffed my FPS by 30+!!! Best upgrade spring
by Sebastian J. on 12/26/2019
"Used for a couple of builds, this is my go to CQB spring brand and tension, I used the M110 and got about 340 FPS.
by Sebastian J. on 12/26/2019
"Good little spring at a good price, use it for a low FPS build and I get exactly 340FPS, I used the m110.
by Joanne S. on 11/25/2019
"Bought the M130 for my Amoeba striker. Very good quality and my gun chrono’d 495-500 FPS.
by Brice S. on 10/06/2019
"Works as intended. A reasonably priced spring that works perfectly in my DMR build.
