Nice! You going to leave it on irons, fit an acog/spectre or go close quarters and red dot it?

Well I never got the slide, literally just got a refund 😕

Just wow! Where is the real @Wo1f that answer was too techie

Most likely dirt or dead bucking: clean out barrel, check bucking isn't contaminated and is clean, check the BBs aren't picking up dirt from inside the mags.

Going on your nuprol chart (which is good gas to use BTW) you want to maintain around 9 bar operating pressure.

WOWZA!

A lot of us long term softers will agree I'm sure, that all guns are mass produced and as such some are not as great as others, CA and ICS I'm looking at hop wise, but for the most part the high end AEGs are made much more consistently. The thing you are really paying for with a TM is that hop unit. And for the most part that is the be all and end all of BB launching. The others listed above are equally or even better constructed, use nicer materials, and support higher FPS than the TM, but all those areas are less important than the hop, of which you can go out and buy x y z 'upgrade' parts for the other brands but just remember they are not always an upgrade! There is a huge amount of trial and error, testing and parts compatibility combinations you'll want to test out if you really want to 'upgrade' it. In a nutshell if you want an AEG and your happy with a realistic 40M range then any of the above suggestions will work, but further than that you have to concede to the fact that upgrade work is needed to shoot further Even sniper rifles are the same. TM MWS is the only gun standard if come across that shoots 55 out the box.

Oh yeh great workout for sure! i find the gun itself is quite well balanced, you need a sturdy comfy rig for the mags, they're the dead weight!

Yeh come on, nice box but where's the candy!?

My new platform for my new 'offensive' pistol build, been waiting all year to pull the trigger on this one

Well I just ordered a Hi-Capa slide last week from CRW, hopefully it'll arrive next be end of week. Once I checked back on the site a few days later and the slide I ordered is now showing "out of stock" so hopefully that means they do keep on top of stock and update the site regularly. I also enquired by email about stock of this slide with another HK vendor and they did reply within a couple days. Just saying it doesn't hurt to ask rather than gamble on it!

Exactly. If you completely remove the tube and the mag is fully topped of with gas (liquid) then there is a very large variation in FPS output due the larger extremes of pressure in the mag, as well as the increased potential of liquid gas vent if first shots are at an extreme angle (IE shooting up or down from a tower for example). The whole idea of the tube is to create a volume for gas. The original TM tubes do this to the extreme limiting the amount of gas storage available. By leaving some tube your having your cake and eating it - more gas capacity / shots per mag and good shot to shot consistency.

On the old mags the fill tube (MGG2-83) used to simply pull out of the fill valve (MGG2-84). I personally havnt had my hands on the new(?) mags, but looking at that image it does indeed look like they two parts unscrew from each other. Either way yes you want to remove the fill tube and cut it in half roughly, I go 10mm longer than the needle on the fill valve. This ensures theres plenty of room for gas rather than overly liquid. Its good practice to have a good look inside the mag and check there is no swarf or debris in there, blow it out, lube the seals with silicone oil and reassemble with some weak threadlock to the screws. Partially fill with good oiled gas and rotate the mags so the oil can settle into the seals etc.

Just take your full valves out, pull out the full tubes and cut them in half, then push them back in. There is absolutely nothing unsafe with this mod. And you've still got genuine TM valves.
