Anyone else pulled their hop ups to pieces?
Test firing my upgraded M4 highlighted an issue with gels breaking up out of the barrel… it was fine without the War Interest hop up, confetti with it on, no matter how it was adjusted. I use Armour Tech green hardened gels.
I decided to pull the hop up apart ( yes, you can if you’re careful) because I noticed the top tongue seemed to have developed a bit of a memory, backing off the grub screw didn’t raise the top tongue up, it stayed fairly low. Figured I’d bend both tongues back so that I had some adjustment again…
Hard to believe but the gels seemed to have caused significant wear on the bottom tongue, it was quite rough… and there were quite a few sharp edges and corners on the inside of the outer case. I reset the bend in the two tongues to get some adjustment back, cleaned it all up with some careful scraping and steel wooling and polished the bottom tongue up to baby bum smooth… works properly again.
Just thought I’d share this in case, like me, you decide to build a dedicated muzzle break or suppressor with a permanently incorporated hop up. They do wear out, and if they’re permanently fitted you’re kinda screwed… maybe the Rizer alloy hop ups are a better option.
