Dynamic Precision 125% Nozzle Spring for TM / WE 5.1 and 1911 Series Airsoft GBB Pistols

"Installed this into an R28 1911 to help un-boneyard it. Indeed, it made the nozzle work again. I will note that this can be finicky to install on a 1911 when trying to re-install the blowback housing back into the slide. A steady hand, a little bit of know-how, and a good chunk of patience came in handy. The red color on this is very useful when it goes flying across a desk during a failed install. Jokes aside, worked very well after being lubricated and correctly installed.

"Works very well, doesn't fall out when turning the unit upside down which makes installation easier.

"Amazing spring worth the price but is really reliable

"Its a great choice if you are running a short stroke build since it improves the nozzle cycling rate so you can load up the next bb faster.

"Frist off the spring is longer than the stock one do its a little harder to put back together but its worth it 40 degree day using propane my kjw kp05 got 7-10 shoots when i installed the new spring i got 15-20 shoots this does not increase gas efficiency but helps the nozzle go faster allowing bbs to load more better help on cold days because the cold makes the gas weaker so the slide doesnt move all the way back that causes the nozzle to not go back so it can load the bb i think this is a great product by uac that help your gun in colder weather
making a great choice

"Came out of the bag smaller than the space it is filling. Using dynamic percision housing and nozzle. Kind of negates the high tension spring if there is a 2mm gap between the spring and nozzle it is pushing. Bought 2 and both were like this.
