About the Madbull Tight Bore Barrel for M28/VSR-10

The Madbull Black Python series inner barrels are excellent upgrades for those wanting more accuracy, velocity, and range. This particular model is made specifically for the Echo1 M28 sniper rifle which requires a 517mm length inner barrel. It is compatible with other sniper rifles that use Tokyo Marui VSR-10 style barrels as well as long as the length is appropriate to your application.

Q: What benefits do tight bore barrels give and how?
A: A tighter constriction from your barrel means the BB is bouncing around less causing deviations as it exits your barrel. This constriction also creates more pressure over the standard barrel so it increases your velocity as a result. The slight bump in power and added accuracy extends your effective range by a little bit as well (though you should not confuse raw power as range).

Q: What diameter should I get?
A: This is a 6.03mm inner barrel which gives you a greatly improved accuracy but won't be very finicky. What we mean is tight bore barrels require more cleaning and are very sensitive to bad ammo. Rigorous maintenance should be performed and feed your rifle only the best and you will not have problems. A tighter bore barrel could give you even more accuracy and velocity but likelihood of a jam when conditions are not ideal is more likely. Most stock barrels are 6.05mm inner diameter or larger amd you can find barrels anywhere from 6.00mm to 6.03mm. On average, BBs have a 5.93-5.98mm diameter. You can see with the variances how easily you could jam up your barrel with the slightest hint of dirt or BB deformity. High quality BBs tend to observe strict tolerances coming in at about 5.95mm +- 0.01mm. Generally 6.03mm is recommended as it is still pretty forgiving and nets you visible positive results right away.

Q: What is "VSR-10 compatible"?
A: In terms of aftermarket sniper barrels such as this, VSR-10 compatible refers to a certain cut in the barrel making it compatible with VSR-10 rifles hopup units and similar. The Echo1 M28 uses the same style for convenience and there are a number of VSR-10 clones on the market that could use this barrel too.

Q: How do you install this barrel?
A: Take this to a qualified airsoft tech for a professional install. Taking apart the M28 and similar is very intricate and there are plenty of small parts to lose or damage if done incorrectly. We do not recommend you experiment or attempt installation without proper research and experience. Attempted installation of upgrade parts voids your warranty on your gun (if it is still brand new) and we will not accept returns on any parts as well. Please do your homework before purchase.

About the Echo1 M28 Sniper Rifle

The Echo1 M28 is designed to be an affordable but highly upgraded sniper rifle out of the box. It features all metal construction with a heavy adjustable fiber stock that makes this rifle feel very realistic. The gun internally uses the common VSR-10 design trigger box so upgrades (if needed) are not hard to trace. The piston and spring guide by default are metal where other cheaper rifles would use plastic. This gun puts out an amazing 500+ fps out of the box making it one of the hardest shooting guns under $200. When you look at what it takes to upgrade a $100 rifle the same way you could easily spend three times as much.
