Question: Will this work on a m4 mk18 CQB
Document: Will this product fit a black ops m1911 scorpion? I bought it it and noticed it had threads to fit a mock suppressor I was just wondering if this would work for me.
No problems here work great. The specifications are 155mm length, 14mm Counter-Clockwise threaded, Solid Aluminum Tube, Caliber: 6mm B.B., Matte Black Oxide finish.The internal barrel that I used is here:http://www.amazon.com/gp/product/B002Y17FXS/ref=oh_details_o00_s01_i00
very well made it is as real as it gets with paying more money installed very well  would buy more
this product worked out great great buy it made my gun a heck of alot more acurate and it just looks nice
not so happy. product does not fit weapon as described. This is a paintball company. not a real weapons parts company. so sad
dumbest purchase I've made so far, it is what it is, just something I thought I couldplay with and enjoy, but it sits around and collects dust, I'm selling it. I'd buy it againonly if I knew I'd really use it. It will do what it should for you, but its just for looks.
This is a simple product to do a simple task. This is meant to go on the end of your airsoft gun's barrel to cover the exposed inner barrel.It does that, and it looks good. Quality construction with licensing marks
It fit my JG M4 nicely, it looks nice on my gun. It does not silence the noise though, its just for looks. Highly recommend
I'm only writing this review to counter rob's review, so bla bla bla bla bla bla bla bla bla bla
I ordered this a few days ago and got it in the mail yesterday. When I put it on my gun, it made it look ten times cooler, especially with the orange tip gone now. It fit perfectly, and gives an extra 155 mm for a longer barrel, which I have already ordered. I have examined how straight this is with the outer barrel, and it seems to be perfectly straight.
Answer: no
