Review:
This a much better than stock for the a5. Shoots a much tighter group from 50 foot on out to 150 foot. Shoots clean usualy in 3 to 4 shots (don't have that problem with the a5 often, no breach brakes in over 7 cases) This is a good inexpensive upgrade. I have a 12 and a 10 that I bought on ebay for less than $15 each new. The only barrel breaks I had were with proball in very cold weather ... about 1 per hopper. I attribute this to the balls getting too cold and brittle.
Some barrels get bad reviews when the problem is the gun and it's owner. Some guns (spyders, BE & cheap BB knock-offs) have such poor velocity consistancy that the gun blows balls and chops know matter what barrel they use. I can't the number of times players come up to me when refing with paint running out the end of the barrel when it wasn't even screwed in all the way.
Conclusion:
Good barrel for $35 excellent barrel for the price when you can get it for $15!
