I'd be more inclined to get a standard MWS and stick the HAO MK16 rail on to give you a lighter, slimmed-down front end, which still looks awesome. For around the same price as an MTR. You also get a 35-rd mag as opposed the 20 with the MTR.
Like @alxndrhllsaid though, perhaps run your MP7 out a few more times and see how you get on before you part with your cash?
@SilentSparkylet us know how you get on with it. I bought one last year and was really impressed on the range, but have struggled getting a consistent set-up so haven't skirmished it yet.
Mine's completely stock and was flinging .3s rapidly and getting range, but a couple of mags have shit themselves (easy fix tbf) and now it's really hit and miss, literally.
Oh, and I got the Angry Gun suppressor without the tracer unit, and BBs just roll out of it. It's pretty loose so I think the rounds are probably bouncing off it. Looks cool AF though 😆
Best, either my TM Devgru, MWS or, as others have said, a gen Odin speedloader (and MWS adapter).
Worst, Viper mesh goggles or an impulse purchase of a drop-leg holster from Amazon, back when I knew nothing. As much use as tits on a fish.
I also had the compact version. Sold it before skirmishing it but on the minimal testing I did with it, it was great, especially on an 11.1v. Build quality was also excellent.
Biggest issue I had was the battery space. I think Airtech do an extension for the buffer tube though, so you can use larger battery packs.
Ah, of course. I play woodland, so go for the heavier end. 0.25s make sense for CQB and the hop should need barely any adjustment for those engagement distances.
I've got hands like shovels and manage it, but if you're really struggling, use a small hex key or flat head screwdriver to help get some purchase. Just don't be heavy-handed
