"This Barrel is the best upgrade I have put into my M4.
I installed this on my G&G M4 and did a little bit of hop-up adjustment and now it shoots amazing, it shoots like a laser.
For only $25 this barrel will transform your stock AEG

"For the price, you can't really complain. Does the job, tightens groupings and overall increases accuracy of your airsoft gun. Only reason I give 4 stars is due to the design of the hop-up window of the barrel, which presents problems if using a flat-hop or r-hop. For whatever reason, the stock window has a slant on front/muzzle-facing side, giving a cross section image sort of like this: \_| as opposed to the standard window which would have a cross section looking like this: |__|. This presents a problem with flat nubs, seeing as the angled part of the hop-up window interferes with the flat nub. Not sure why Matrix decided to cut the window like this, but if you're planning on using a flat nub, you'll have to file or mill out the rest of the window for it to work properly, which can present problems (burrs from filing the barrel coming in contact with the bb) if you don't have the tools to do it cleanly and correctly.
