Well it definitely was a good barrel. The price was good, it was easy to install. It made the gun a little louder but not by much. I did'nt notice any increase in fps. My only problem with it is its durability. After about a month or so my gun started shooting real crappy. The inside of the barrel had started to wear down. Looked almost like chipped glaze or something. I really like Airsoft GI's products but I would'nt recommend this.
Good price. Increased accuracy. Light weight.
It starts to wear down after about a month or two. Makes the gun louder. Accuracy stinks after it degrades.
Amazing product! A must have for ASR owners. Without it, my ASR (with upgrade kit) had a 200 foot effective range. Now with the tight-bore installed it now has a 250 foot effective range and I hit the 200 foot target much more than before. It definitely increases fps by around 15, but on the other hand it makes it sound louder. This could be a good thing as well, because it makes it sound more realistic. Be warned, howerver, as it takes around 100 shoots to be broken in (at first I thought it was terrible but after 100 shots it was shooting perfectly). Overall this is a fantastic upgrade you should definitely get if you are an ASR owner.
-Increased range by 50 feet
-Increased fps by 15
-Increased accuracy by a lot
