Yes UK. No my DMR has a 410 inner in it and I do have a spare 370 if I need to drop fps in the warmer months. The M4 with the 310mm inner barrel + a few other minor mods is clocking around 330-340 fps during the winter on Nuprol 3.0 and black. My MWS DMR build with 410mm inner barrel and ice pick is doing 410-420 fps. all above based on 0.2g bb. What range are you getting with that? with my 410mm inner and ice pick I’m getting 60m accurate 0.36 (haven’t got a longer range to test on on yet). But for some reason I get the odd bb fly off. Annoying that really. Using a 60deg MR HOP, stock Hop Unit and SixG nub.

I’ve put a 310mm in mine and that fits but not sure what length is left.

I believe the stock length is 250mm.

CTR fits lovely!

That’s great thanks. I did try and search but couldn’t directly find anything. Hoping to use the 10.3’’ barrel to match the RS version, but only seem to find MK16 versions at the mo.

Hi guys, I’m trying to build an MK18 from an MWS and will be using the Madbull MK18 Handgaurd. My question is what outer barrel do I need? I assume an MK16 (z parts) outer barrel would work but obviously not the correct one to adopt for a build like this. The real deal one would use an M4 barrel but don’t know of any third parties that do an M4 barrel without the need for the front sights to mount the gas router. Any help would be massively appreciated.
