MP5 Metal Front Cocking Tube Slipping Out

[Jerold]

Cool!

Thanks for all your help!
I'll just take the plastic parts with me to the hardware store to size up the copper tube.
If I can just figure a way to get my battery to fit into my RIS unit, then I'll be set.

Full stock
Empty LAM module,flash light
Seem to be the most common options

If your lucky you might be able to float a stick battery inside the copper pipe, but I wouldn't hold my breath.

I actually use red and they still come off pretty easily, I think there are two different types of the red, one of them is pretty permanent, the other is like the blue. Just gotta pay attention to the label.

just got home and pulled out the original plastic MP5 body and I understand how the copper pipe can definitely do the trick. I forgot that the tabs were on the receiver and not the front tube, so it actually works out perfect. The copper pipe will stiffen the connectionbetween the 2 parts and the tabs will help to keep the parts aligned properly.

**UPDATE**

I was inspired late tonight to fiddle with all the advice from this post.

I found a piece of copper pipe and pipe cutter in the shed that fit perfectly into my factory plastic front tube. After some test fitting, I could only get about a bit more than 1 inch into the receiver because the top plate peice that spans both sides of the metal receiver doesn't copy the inner contour of the rounded receiver. I didn't want to totally take the gun apart to shave it flush, but it would be possible. That way, you could get about 4-5 inches into the receiver. Funny thing about the cocking handle - and timely. Stupid thing broke off, so I didn't have to take apart the sight to get it out. I can slide an entire 5" into the front tube. It bottoms out at 5" and helps when you jam it into the reciever for final assembly. The pipe totally fits snug into the front tube, so no cocking tube assembly anymore - kinda looks cool with the copper color showing. I couldn't get the pipe into the metal version of the front tube, so I decided to reuse the plastic front tube. It actually doesn't look too bad - I've upgraded everything that can be into metal so a bit of plastic works for me. The inner diameter of the metal tube is a shade smaller than the plastic one. I think that I can hammer it in, but I'll try it later. The plastic tubes works better for the battery and the wires since the metal tube didn't have enough space and the battery had to be jammed into the RIS unit.

Still unhappy with the 3 lug muzzle and front sight assembly. My modified grub/hex screw was just eating into the soft metal of the muzzle and if I screwed on a supressor to the muzzle, the weight of it would just grind the muzzle against the screw till it loosened up. I tried looking for a replacement MP5K front sight on the internet and NO ONE carries any type of replacement front sight for the MP5k. Not to be defeated, I decided to fill the empty space, so I wrapped 100mph tape around the muzzle that goes into the front sight, trim off the excess, cut out the alignment slot and peel off layers until I got a tight fit. Once in, I applied inward pressure and tightened the grub/hex screw up from the bottom of the sight and that sucker feels pretty solid. It actually came out way better than I thought it would.

Thanks for your help again!
