Egon_247 Posted March 9, 2023 Posted March 9, 2023 My boy has bought himself an m89 ump45 from DE and only being little (he's 12 but a small 12) and the stock on his gnu seems a bit too long. Anyone ever shortened a stock? It's the folding type...

Had the same issue with the G&G UMP I owned a good while back - the length of pull was too much for what is ultimately a CQB gun. Ended up selling it because of the stock. I know there are 3d-printed buffer tube adapters about - but I have no idea if they are compatible with the Double Eagle version. Egon_247 1
Krisz Posted March 9, 2023 Posted March 9, 2023 I would try to retrofit a shorter UMP stock first something like this: https://www.sixmm.com/en-gb/products/cyma-mp5-ump-foldable-airsoft-stock-for-mp5-mp5k-aeg-series. Ofc it's airsoft who knows if it's compatible. More expensive solution is selling it and buying a Double Eagle M917C UTR45 which is very similar looking gun. Egon_247 1

I'd say that won't work as the DE one has a battery hatch in the rear of the upper receiver. That said, you might be able to get the hinge pin out and swap the actual stock part over. 2 hours ago, Egon_247 said: My boy has bought himself an m89 ump45 from DE and only being little (he's 12 but a small 12) and the stock on his gnu seems a bit too long.

I'm thinking I might be able to cut the butt plate off and reattach a bit further forward. Hmmm.. I can hear the a team music coming on....?? Nick G 1

You could certainly try - I mean TommyBuilt G36s and UMPs are made by reworking the plastic of the civilian H&K models - welding new sections of receiver together. There are quite a few videos on YouTube about using a soldering iron to weld broken plastic pieces together. It would probably look a bit gopping on your first go, but you could use a cheap 2nd hand G36 stock to practice on. Just try it in a well ventilated area. Egon_247 1
Egon_247 Posted March 9, 2023 Author Posted March 9, 2023 Ahaaaa. Apparently there's a 3d printed doodad that allows you to fit an m4 stock to the hinge....might go looking for one of those..... Lozart 1
Egon_247 Posted March 27, 2023 Author Posted March 27, 2023 Well, as i cant stand threads that just die off and no one knows what happened.....this happened.... I bought the M4 conversion piece (aliexpress, was about £8 and is 3d printed) and fitted it. The M4 tube mounting screw was about 10mm too long but an M6 nut and a couple of washers and jobs a good un. While i was doing that, i did actually cut his original stock down and with some M4 countersunk bolts, a bit of plate and some swearing, i managed to cut about 12cm off and remount the shoulder part. I'll get some pics tonight when i get home from work but he's a happy chap again. So happy that he bought an MP5. KIDS!!!!! Nick G, Cannonfodder and Lozart 3
