Just a heads up on the sr25, the mosfet shuts the gun off after 30 mins of not shooting. It's not a big deal, but in between games it could shut off. Just unplug the battery and plug your battery back in. My buddy and I thought his was broken until we was informed of this.

sr25 qbs right? I picked up a used one never used. I dig it but hopefully you'll be better if I mention a few things. mine was 16" barrel and had to change out the outer so I can run it honey badger style or req. flashider but if you want to use any muzzle device you might be better off having a tech. I've got krytacs, Avalon's and g&g's and if all were combined still wouldnt have been 1% a hard to get it off my sr25. I sadly destroyed it so its still not right. I tried everything and it literally twisted all the barrel and handguard nut back into the gearbox. still didn't come off. I had to replace the outer barrel and have spent countless hours to get everything semi lined up still not and is not capable of repair. it also caused a problem I saw in milsim father video on his same one the quality is above is price and the finish is great plus mine destroys all with its charging handle feel. its the most likely real and is so satisfying it makes you want to do awful things to it because its almost to an excitement. its like wrong and nobody should be aroused like that without a female present. I hope yours is as Good as mine was. its is sadly jacked up as are the other problem area parts . the grub screws to hold that long heavy rail are either there for a joke or some law but they are not even close to being strong enough to hold a plastic pdw one.. the best thing to do is if you take it a tech they would be able to bore a new hole with tread for an adult size grub screws. use some loctite if not because over time they will back back out and they a crappy metal and will strip the Allen before you will tighten it to not move. its still a great 110. you got spot on taste my friend. cheers

What brand and website did you buy it from?
