"This is a good air nozzel. I installed it in a echo 1 m4 with ease. THere was a small problem that may be just in my case but i had to file about a bagillianth of a millimeter off the front that loads bbs into the hop up. My gun would not feed the bbs beforehand because the nozzel was to long. Other than that great quality and i noticed about a 10 fps increase in my m4.

"This thing is great. I bought a boneyard m4, and it had a bad air seal, so I put a spare piston head, cylinder, cylinder head and this nozzle in it. It required a small bit of sanding to get it to feed, but your gun's hop-up chamber may be slightly different.

"Recently bought 2 of these. Well made, double o-ring, etc. However, be aware that these have a small inner diameter and don't fit many cylinder head nozzle tubes (too tight). If unsure, buy a cylinder head and nozzle that come together as an upgrade kit to ensure proper fit.

"Pros:
-Solid build
-Great look
-Smooth operation
-Oring seal

Cons:
- Doesn't fit some M4 models

Overall:
I really liked this nozzle. Gave a good seal and worked perfectly, once I found a gun it fit. I initially put it in my JG based M4 and had major feeding issues. Checked the nozzles length and found it was a mm to long when compared to the stick nozzle and wouldn't let bbs into the hopup unit. Swapped it out for another nozzle I had and it worked fine. Put this nozzle into a friends gun, with a Jg gearbox??, and it worked perfectly, giving a good seal and feeding fine. So in the end, very nice air nozzle, but some mods might be needed to work in some particular gearboxes.

"Excellent Nozzle, has great performance, however this will not work with a Classic Army M-249 without modification and sanding down the front of the nozzle. It is ~1 mm too long and will prevent the magazine from feeding. Once sanded feeding issue disappears and nozzle works great.
