"Very good inner barrel, increase the shot precision, even for a 9" AEG like the G&G CM 16 SRL, which fits perfectly.
Good choice for upgrade!

"My bolt br47 hop up chamber is a little bit open after the change. But shoots straight, much better than the original 6.0 bolt barrel.

"these are probably the best 6.03 barrels on the market, but to be honest the improvement over the stock krytac 6.05 is very minimal, about the same range, and slightly tighter groupings (with .3 bbs) I think it would really benifit from a r hop or what ever bizarre hop up everyone and there grandma is using these days, never mind the fact that these barrels were designed for it. if your particular barrel is out of stock I would not sweat it because stock krytacs are pretty much the gold standard in allot of ways, accuracy is one of the best on market out of the box.

quick side note, these do come with o rings to stabilize the barrel
