I have (mostly) finished my mk18 build. I’m going to be looking at other torch options, mainly because I’m not happy with the one I have and I’ve also seem to have misplaced the pressure pad! The information in this thread has been really great, just a quick thanks to everyone! The main upgrades are: Laylax 6.03 250mm inner barrel Modify hop rubber Laylax hop arm (will pick up a super nub in the future). Mad bull mk18 rail a low profile gas block and spacer (both of which I can’t recall what they are exactly) Magpul stock, AFG and grip Raptor style charging handle Vortex crossfire red dot with back up irons There was a few issues with fitting the rail that took about 30 minutes to resolve. I’ll add my mistakes here: - The coupling that has all the screw holes does not have a continuous gas tube hole. So you either have to drill a hole, or cut the gas tube down. I would really recommend against drilling the hole, as there is an internal step down that leaves no room for error and you may end up splitting the coupling. I started drilling and then stopped once I realised it wasn’t an easy exercise with the tools I had. - The barrel nut has to be tightened a fair bit to stop the rail from twisting very slightly once it’s on. I also added card shims either side of the tabs of the coupling. The tabs slot against the receiver and the shims gave it a tighter fit. For now, it’s very sturdy and in line. I quite like like the black finish on the rail, but this is preference. While it performs great, i have to say there isn’t hardly any difference from the stock barrel. Although I’ve only done some basic testing. The accuracy of the stock rifle (and barrel) is quite decent. Also, by adding the 6.03 barrel the fps stayed the same (around 295 on 0.25s). I’ll keep the laylax hop arm for now, but will likely get a nub in the future. I know a lot in this thread use heavier bb’s and reach really long ranges, but for now I only stick to CQB and urban sites. I’m quite new to airsoft so that may change few months down the line. I’ll probably end up playing around with it more! Oh and I should also add she hasn’t been skirmish tested yet, but that’s coming up in three weeks. I only have a total of 3 mags though!

Thanks so much, really appreciate the help. I think I’ll try out the 250mm Orga and test to see how it is. Interesting on the ASG Ultra Air, is there a reason for that? Is it damaging in any way? Now im worried about the madbull rail, it’s on order and coming soon. But without the adapter I can’t fit it. Is this because of mad bull, or do you think its a specific issue to the mk18 rail?

Hi All, I recently picked up an MWS CQBR (not even skirmished it yet). I’ve been following this thread a while. I have a few questions around some upgrades - so far I’ve picked up a magpul CTR stock, grip and AFG, madbull mk18 rail (9 inch), gas block and a Laylax hop arm. Also have a vortex red dot and some flip up sights to complete the build, together with a Maurui silencer. I have a few questions and would really appreciate some help if possible, new to airsoft and never built a rifle before. Although I’ve seen a lot of videos and am fairly comfortable to do it myself. - Is the super nub really noticeably better than the Laylax hop arm? I’ll likely stick to .25 to .3’s. - I’m looking to find a barrel nut adapter and can’t find them anywhere online. I’ve been searching for a PTS one, anyone know of anyone that has these in stock? - Will the madbull rail need any fitment at all? - I’m considering an inner barrel, possibly an orga Lex 05 250mm. Will this increase the FPS and be better overall when compared with the stock barrel? I want to keep it firing within site limits. - Also, what is the stock FPS with something like ASG ultra air with moderate weather conditions? I’ve had people say it’s 340 to 360 FPS stock. (Going to need to get a chrono soon). Thanks Mike
