"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.

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

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

"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.
