Matrix Airsoft Barrel Thread Adapter (Model: 14mm Negative to Negative / 1.5")

"Good quality, but soft so dont force it if its not smooth.

"Works Perfect For Adding A Large Muzzle With Smaller Hand Guards!

"The finish is nice and threads are good.

"i got the 14mm negative to negative 1 inch. the whole thing is 1.5 inches. It's one inch if you don't count the threaded portion.

"14MM NEGATIVE TO NEGATIVE / 2"
This will increase 2 exact inches to the total length of your barrel (without the thread)

"Similar to other reviews, I ordered the 2" size which is actually the total length (including the threads). Mine was actually a little bit larger; it was 2.16 inches (55mm) from top to bottom. The area before the threading is exactly 1.5 inches with the threaded area being 0.66 in. Does its job and feels very solid. Would recommend for anyone else looking for an extension/adapter.

"Contrary to other reviews, the one I got extends the barrel by exactly two inches.

"Received this outer barrel extension this week: it is a little thinner in diameter than what I expected, and is 2 inches in TOTAL length, also not exactly what I was expecting, so it only actually extends your outer barrel by approx. 1 and 3/4 inches not 2. Also it is a dark black not the grey that is pictured. I had no issues with inner barrel fitment, I am using it on a WE SOL GBB M4 with the OEM inner barrel.

Pros:
1. Very light weight - metal is aluminum
2. Works as intended

Cons:
1. Color is dark black, not the grey that is pictured
2. Is 2 inches in TOTAL length, making it a 1 and 3/4 inch extension in reality

"This extension only measures 1.5in. Does what it's suppose to, unless you're looking for something that's 2in.
