UNW P90 50cal MAG MOUNT FOR THE Umarex T4e HDR50 TR50

this mount can be used with the 50 cal version of the UNW P90 mags that holds 37rounds.

as you can see on the pictures are there a view options when it comes down to the front morning part. this is so you can have custom look. but at the same time also to make this mag mount more flexible for the current mags and future designs.

but the original P90 design does help in guiding the mags into place. so in case you don’t like the tall look to the original the low wigged is a good middle ground

I do say that the grub screw needs to be at 2mm in hight. that functions to activate the magazines. but it’s possible that is need a slight adjustment. this will be covered in the UNW P90 PDF. I do like the idea of having a smooth top on the grub screw so that is why I like it to be installed the what it’s shown with the hex key mount hole at the bottom of your Mag mount.

the slide. you want the slide to move smoothly and not get stuck when it’s fully compressed. this can be because of support remains or elephant food. but you can also play around with the spring tension if you like I used to use 2 springs with a 0.5mm wide instead of the now recommended 0.6mm wire. since I noticed that adding 1 extra spring with some stiff wire was actually a lot better. so you may want to play around with it so the slide is sliding al the way forward every time when the mag is placed in the mount.

UNW P90 HDR50 features:
in case you like to use shaped projectiles mix it with the hi capacity roundball mags then it’s easy to switch back from mag fed to the stock cylinder system, just remove the mag. or leave it on there when it’s empty. and remove the feedneck cylinder piece and insert a normal HDR50 cylinder.

besides that does it give you some space to place some M-lok attachments.

compatibility note:
this mag mount designed around a stock HDR50, but I did see that there is a extended barrel option from HOMEDEFENCE-24 and I did made a shroud option for that one as well. with the assumption that the barrel diameter is not thicker then 20.50mm

materials needed:
2x spring 6mm OD, 0.6mm wire, 20mm long
Note: you can add one more if you like it to give the slide more power

2x M2.5 Bolt 16mm long

1x M5 grub screw
Note: this needs to stick 2mm up from the mount, use some calipers for this.

1x M5 bolt 25mm long

3x M5 bolt 35mm long

2x M3 bolt 30mm long

2x M3 bolt 10mm long

parts for feedneck:
1x M3 bolt 6mm long
1x spring: 0.3mm wire, OD 4mm, 19mm long spring (you might want to play around with this)

print settings:
0.2 layer hight should be fine.
you can use the 8 layer walls and a 40% infill.
but personally I moved a bit over to solid prints just to give it more strength in case things go wrong on the field…

Print-bed requirement: the files are designed to work on a ENDER 3 Pro, that haves a print volume of, X 220mm, Y 220mm and Z 250mm. with that said it’s not necessarily maxing out to those sizes…
