MadBull Black Python 363mm (M4A1) Tightbore Barrel 6.03

Black Python is MadBulls experimental product. By using a hard coating process, this barrel can provide the smoothest inner barrel surface and reinforced structure.

Works in most Marui compatible M4, XM177, SR-16, SG551, CA SLR-105 Compact
Only works in AEGs. Will not work in spring guns.


NOTE:
Adding a tightbore barrel to your AEG is some of the best money you'll spend in Airsoft. It will greatly improve your accurracy and hence increase your kill ratio on the field of battle.

It also usually adds about 10-20fps to your gun because there is less air escaping around the BB as with stock barrels. This will also add some distance and accurate range to your weapon.

Your choice of BB will be very important. You must use high quality BBs to ensure they are consistantly round, otherwise you will experience jamming. We recommend ToyTec, Excel, KSC and TSD BBs, along with other truly premium brands as your best bet.

No more cheap BBs, but who cares when you're zinging guys out at crazy distances...

Hands down the number 1 in value
Chavez (New Lenox, IL) 12/2/2009 9:02 AM
Through 6 guns i have used nothing but these. This tightbore is the best value you can get. Performance is amazing for the cost and quality is excellent. Are there other barrels out there that will perform better? Sure...but you'll also be paying three times the price for them and getting marginal improvement.
