I finally managed to get back to South Herts Airsoft today. Arriving in the morning is when the only negatives happened, first I'd forgotten my BFG reloading tool and then I reaised I lwas almost out of green gas. Unfortunately so was the on site shop. This wasn't so much of a problem though as with the low temperature,  and the site being woodland, I wasn't expecting to use the pistol or shotgun much.   Numbers were low at just under 20 people, but with it being a small site this wasn't a problem as I could choose whether I wanted to go loud or try some sneaky shenanigans.   We played a variety of games including capture the flag (including one version with a twist where a third team with limited lives started defending the flag), king of the hill, escort the VIP and others. Gameplay was excellent with nobody complaining about hit taking or overkill, just happy faces around. The way airsoft should be.   If you're near Hertfordshire I definitely recommend paying them a visit

Fine rain is a bastard, piss wet through. Here's a lovely picture of me where I'm completely covered by a tree branch looking very tactical and "my boonie was ordered last minute and is completely the wrong colour" pilled: The hop unit that comes in the CYMA Plat. SLR Rifleworks AK is complete wank, by the way - .28s, .30s, .32s  all either dribble out of the barrel or overhop completely. Tried three different rubber & nub combos, and a completely new barrel, but apart from that being extremely annoying it was a good time. Come to think of it, all AK hop units are apparently wank as my mate's recently built by Negative Airsoft LCT RPK is currently sending 0.32s to the moon with zero hop applied, which is a shame because he was really looking forward to using it. I just need to move to an M4 like everybody else..  

Mine are showing as in transit, so with a bit of luck , may get them in a week or so. If the 33g threads are to large I'm thinking to try a couple of 25g ones. Those are the same thread as 12g as far as I can see and 2 x 25g should last a game .    As I think you suggested, it might be possible to drill and tap the adapters for larger capsules. As long as it'll all fit in the box mag I'll be happy.
