Both are 3rd gen mags and have been super finicky in my experience (unless it's just user error....)

I tested with both mags (one with an oring and one without). I can get to 20g of gas for the mag with the oring, but the stock mag seems to max out at 8-9g before gas spews....

Ok here's what I tried. There's a definite improvement and I'm now able to get through half the mag before they dump gas (previously I was only able to get out 1 or 2 shots). I was only able to get through a full mag once across 10 or so attempts over the last few days.... any ideas? Steps tried: 1) Chilled mags in fridge prior to filling 2) Purged mag of air at the start of filling 3) Weighed out mag for +20g gas 4) Warm mags up to useable temp

Thanks guys - appreciate the responses. I have tried purging previously with no success, will give the other recommendations a try later today and report back.

Having a bit of an odd issue with 2 MWS mags on my mk18 - one is bone stock and the other has an oring dropped into the fill valve. Being able to unload both mags just once after filling with green gas is a crapshoot. I can get 1 or 2 shots in before the mag discharges and dumps all remaining gas. I have better luck with the oring mag than the stock one, but both have this issue. Has anyone encountered this before or have any ideas? I just want to be able to use my mk18 reliably 🥲 Edit: more info if it helps..... i have this issue regardless of whether I fill in 1 second bursts (4-8x) or if i fill for 30s continuously.

Man - you guys are the best. Thanks for all the responses. @Davegolf - Thanks so much. I will PM you for details. The grip is not a clone as far as I can tell - it did mate well to the receiver and only "wobbled" after this happened and the bolt came loose. And LOL yes this is what inspired my username. @Jacket - Thanks Jacket. Will PM you and see if we can work something out. @alxndrhll - Thanks for the suggestion - I was thinking along similar lines and am trying it as we speak (waiting for the glue to cure lol) @C-Diddy - I used the OG bolt - i used a socket rachet which may have been the wrong call in hindsight lol. @AlphaBear - thanks AlphaB. Figured it wouldn't be covered, but thought I'd ask. Appreciate you guys!

Hey guys. Received my TM MWS (mk18) yesterday and happy to be joining the MWS gang. I swapped out the stock grip today for a magpul K2 and noticed alot of wobble after some use. Attached is what I see after removing the grip. I'm super disappointed (mostly at myself, I assume I may have over-torqued the bolt?) but am I totally screwed here? Do I have any options other than replacing the entire lower frame? I also assume this is not something TM's warranty would cover since it happened during a modification. Any help/insight would be much appreciated.
