I bought this barrel for my new DMR set up. and let me tell you its beautiful. it gives your gun range and accuracy and its a really nice addition to your gun. i would suggest this barrel for people who are looking for range especially. put this in with .30 bb's and you will easily hit 220 230 feet. you can't see much of a difference at close range though. a regular tight bore barrel would suit you just fine in a close quarters situation. But with a dmr set up this is the perfect barrel. the diameter is like 6.06 so you may say isn't a tight bore barrel better but if you watch the video airsoft gi did on the miracle barrels you will understand how they work. for me i fell in love with the barrel and i will never be getting another one!
huge range again
perfect for dmr
not really any at all
price is a little steep but you get what you pay for and this thing is beautiful!
overall a 5/5 for me and i would recommend it to any player with any dmr style role or any role really!
