AIM High Precision Steel 6.03mm Airsoft AEG Tight Bore Inner Barrel - 590mm

"You really can't beat this deal right now.

Threw one of these into my A&K SVD and gave the hopup a little twist, accuracy went up pretty significantly, consistency also went up, even without messing with a new hopup, it started putting multiple bbs in the same arc, it didn't do that with the stock barrel.

Offhand in standing position, firing at a torso sized box at 110 feet out of sights with .28 gram bbs, the results of old and new barrel were as follows:

Old, stock brass barrel:
1/5 hits on the box, 0/5 If I didn't compensate for wind or curve.

New, 6.03 AIM Steel barrel:
5/5 hits on the box, 3/5 when I didn't compensate for wind.

As you can see, its a pretty significant improvement, and for $22 on sale, you really can't beat it.
I highly recommend this if you have an m16 pattern rifle or A&K SVD and don't want to blow the cash on a 6.01 barrel.

"I love this barrel!!!
I bought it for my A&K Dragunov SVD and it fits perfect, greater accuracy, greater fps!
Highly reccomend 22$ very cheap!!!
