Great barrel for long shots and very accurate. Had no balls brakes in it yet and had it for 3 months.Would buy it again any time and some of my friends even use it as well. 5 stars

I have put about 2000 rounds or so through this barrel on my Spyder MR1 and it is definitely a step up in accuracy from the stock barrel. The price was right. The MR1 is a little on the loud side, so an aluminum barrel will add a little to that condition. The only real weakness that came up was some CO2 freezing in the barrel during a sustained shootout. That can be addressed with an expansion chamber or switching to nitrous. All in all, this is a really good deal for about $20 plus shipping. 4 stars
