BuzzBee Sentinel Spring (100FPS)

Regular price $5.00 Sale

PRODUCT DESCRIPTION:
This precut BuzzBee Sentinel spring is cut from a K26 and has been tested to match your blaster. With an increase in about 25+FPS from the stock average of 75FPS, this spring is the perfect simple mod for more power and accuracy. This spring has been custom cut and tested to fit the BuzzBee AirWarriors Ultra-Tek Sentinel blaster.

On installation we found it easier to access the plunger from the back end by carefully unscrewing and removing the catch mechanism. You shouldn't need to take any other parts out, then just go ahead and slide your new custom spring on. Another side note is you'll need to remove the blue plastic cover over the magazine opening in order to access the last two screws for removing the shell.

• 100+ FPS

SPECS:
• Cut-to-Length Compression Spring,

Great Spring, but maybe just a tad long

I bought this to restore a Sentinel that had been abused by the previous owner. When I put the spring in at first, it made the prime considerably harder, but nothing an adult couldn't do. However, it also made the trigger pull very hard, to the point I had some serious issues pulling it. I ended up cutting half a coil off, and that made so much of difference. Trigger pull was very comfortable, the prime was a bit more comfortable, and I think there was insignificant (if any) drop in FPS (don't have a chrony, so I can't be sure, just based on range and impact force at point blank range). All in all, a great spring, but I think cutting half a coil off makes it even better.
