Precision barrels are best described as an inner barrel with a diameter of 6.04mm or less. Precision inner barrels allow for better compression, improved accuracy, and in a few cases increase muzzle velocity. Although precision barrels often require more maintenance and cleaning, they can give an AEG a greater range and improve the overall performance of an airsoft AEG.

For: Bravo Steel 6.03mm High Precision Inner Barrel for M4 CQB (285mm)
This is a great barrel. Great polish on the inside, no burs around the window cut, and a perfect crowning. It's stainless steel (tested with magnet) and appears to be blued.
Installed with a G&G bucking/nub and the Bravo hopup unit (also a great unit; very similar to the NEO chamber). Accuracy tests show this (337-340 fps) performing better than my KWA M4 (390-400 fps) with 455mm madbull python.
For reference: I've used G&G, KWA, PDI, Madbull, ASGI and Systema barrels; I'd buy one of these any day over the others. It's very close to PDI accuracy for half the price, and better than any of the others in my honest opinion.
No burs or any other deformation
blued (appears to be atleast)
