Systema Precision M16A1/A2/VN AEG Inner Barrel (509mm)
[Y01H06B][00162 / SYSM16TN]New to airsoft? Here are some safety tips for airsoft guns that we recommend following.
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.

I have used Prometheus, Madbull V2s, G&G and DB Customs. I'd have to rate the Systema better than the Madbulls and the G&G, less than the DB Customs and Promy. A fine barrel - but a high price.
Fit in my CA m249 MK2 very well. The gun had some light mods to it that increased its ROF to about 40 BPS and as a result gave the user the accuracy of a storm trooper. This barrel correct the accuracy issue.
Pros:
-Increased accuracy by about 100 feet
-Increased velocity noticeably (I don't own a chronograph to give an accurate test)
Cons:
-Slightly too fat to put the little brass ring back on.
-Too fat for the clamp near the hop up to go all the way down into its grooves. This is made worse with the addition of the "Madbull Blue Hop Up Bucking".
note: these are both issues in regards to a barrel made for a different gun. They won't come up if used with the correct rifles.
