MadBull Airsoft 14mm CCW Steel Outer Barrel Extension (Length: 2")

"full metal, works perfectly, easy install, highly recommend. Fits on my Krytac Trident CRB Mark II M, I would also suggest getting the Krytac O rings and spacers to compliment this

"Does as described. Someone reviewed it saying it doesn't work with the lighter s, it does. You just have to try screwing it the opposite way.

"Perfect as described, needed to cover my barrel so I could add a tracer unit

"This thread extension is 2" not including threads, so it's 2" plus the thread, so if u want a thread included with the length, this one might not be for you, otherwise its a great extension to have.

"Got this for the g and g arp 9 to be able to add a mock suppressor/ tracer unit on it. Fits wonderfully and very sturdy. 1 inch was all it needed.

"Great little thing. Nice metal, nice finish. Comes with a thin oring to put on the original threads and the bottom of it has a bevel to screw down tight and have a barely noticeable seam.

It's light and does the job. Turns my M4 from a 10.5 into a much neater 12.5 build.

"This is a nice, hefty piece of barrel, and other than that, there is not much to say.

Pros:
Excellent pricing
Obviously not pot metal
Totally a really dark grey (think M4 barrel) and not black

Cons:
No set screw hole
Definitively a really dark grey (think M4 barrel) and not black

"Bought the 1" version so I could use large barrel attachments (like a tracer) at the same time as my P90 Swordfish mod.
It's a bit wonky getting it on straight - it keeps wanting to go on crooked. But after you play with it a bit, it will go on straight and stay that way. Fixed my problem completely!

"I purchased this to extend past the Mlok rail on my ARP9 in order to install a tracer unit(14mm CCW). The tracer unit is 14mm and threads onto the ARP9 barrel just fine when the Mlok is removed. The female end of the extension unit threads onto the ARP9 barrel perfectly. However, the male end of the extension unit will only turn about one thread into the tracer unit before it will not continue(I'm talking had it in a vice, wrenching with pliers, afraid it was about to crack). When not fully threaded, the tracer unit is crooked and does not fire BB's straight. I do not have calipers so I cannot check to see if the threads are simply too large, the thread count appears to be the same and there is no visible damage on either thread set. Overall the extension unit took a solid beating so I think it was made very well. I'm disappointed I'm going to have to purchase a different brand to see if a different extension will work.

"Did not work with the AceTech Lighter S. Threads seem right, but for some reason did not allow the tracer to screw on. Please save yourself time, money and frustration by NOT getting this.
