So I have been doing some experimenting wit the MWS ever since I ran into my overhop issue. For those who don't know, essentially while firing, something is causing the hop dial to turn back, applying drastic amounts of hop with each shot. For reference, I use 0.32 g BB's and propane. The following is a list of upgrade parts I have installed:
- G&P Roller Bolt (replaces the stock end piece on the bolt carrier for one with bearings)
- SixG super nub
- SixG high speed buffer
- Modify tan bucking
Of all these parts, the only one I could see affecting the hop dial might be the roller bolt, as it could have misaligned the bolt carrier and cause it to interfere with the hop dial. Aside from the nub and bucking, I removed the upgrade parts and reinstalled the stock ones. This did not solve any issues.
When testing it out, I set the dial back by 14 clicks (out of the approximately 21 clicks the dial can move). Inserting a new magazine and charging it, within 5 shots do the BB's begin to overhop. I remove the magazine, and observe that the dial is mostly, if not all the way turned to maximum hop. After resetting the dial to 14, the rest of the magazine fires consistently, sometimes with an added click or two of the dial. After the magazine finishes, a new one is inserted, and the bolt release is pressed. Then again, within 5 shots does the dial get pushed back. This leads me to believe that whatever manual input of loading a round (charging the bolt/pressing the release lever) leads to the dial being forced back.
Honestly I'm dumbfounded as to what is causing this issue. I've tried removing the hop adjuster and retightening the dial screw. It's seated perfectly fine in the upper receiver as well. If I get desperate enough I may just fill part of the dial cavity with epoxy to create a "hard stop" for the hop up. Either that or try switching it out with the one Guns Modify makes, but I'm not sure what else I could do. If anyone has any suggestions or similar experiences, please let me know.
