Mad bull blk python version II barrel. Lonex bucking. Ufc ump 45 outer barrel and silencer. X2 high cap mags with dummy rounds. X2 viper dbl mag holders.

Stock 200mm barrel against the 300mm Mad bull blk python tight bore. In metal outer barrel conversion. Works a bloody treat now, very happy. Hoping for better accuracy over a greater distance.

Problem solved. . Was the stock set up. Got a better longer barrel and Bucking.

I like mine, it's a good size and with the upgrades i've added it's turning out to be a little belter.

I'm not happy with the build quality of the plastic hop up that you get standard with the UMP 45. I've seen a guy change his for a 5uk which is made for the H&K g36. Has anyone else done this or know of anyone who has? Cheers Muzza This guy does the same but with a Wii tech g36

Nice one. I'll give it a try.

So I took it apart again, checked it all out, then took my time putting it back together. The thing fires upside-down but not properly the right way up. I have to jolt it,seems as if they are not getting to the top properly.

Cool, Hoping i can resolve this.... as the silencer looks so much better than the tacky plastic outer.

........... oh nooooooooo!!!!

3. the motor is fine it's a brand new gun .. not been used yet. 4. The inner barrel and hop up unit came out too, however the inner an outer do not touch. 5. Silencer removed and fired still no BB's passing. will try options 1 & 2. Cheers Muzza

Ive added the new outer barrel and silencer. The inner barrel & hop up parts have not been messed with, However the gun will not fire? ive tested it with old & new maggs but still not shots fired... There is air passing out the end, but the BB's dont seem to be taking?? I've then had the inner barrel out and stripped and rebuilt, but still no joy...... Any ideas??? I also have a new inner on its way. Madbull Airsoft Black Python Ver.2 6.03mm Tight Bore Barrel (300mm) .With Lonex Hop-up Rubber 50 Degrees. Cheers Muzza

Cheers, I'll go for the 6.03. Muzza

Thanks, I'm trying to sus out the dimensions of the inner barrel. Stock is 200mm and i want 300mm as the silencer will allow this. However im not sure on bore width?? Muzza

Just bought a metal barrel & silencer kit for the H&K UMP 45. Being so this has made it possible to fit a longer inner barrel. the Factory one is around 200mm, i'm looking for 300mm but im not sure on the width? Can anyone help with this. Some guy on youtube had a 6.01 tight bore but he had swapped out his plastic hop up unit for a ally G36 one... bit confused here. Any help welcome. cheers Muzza

New to this, Just got myself a starter kit, Which consists of a H&K UMP 45 Two tone, With a reflex sight , FWD grip. Uprated battery , uprated mags with dummy bullets. I was a bit annoyed with the fact the outer barrel is plastic. So i bought a metal outer barrel with a 8" silencer combo. Cheers. Muzza
