Well MB03 Bolt Action Rifle. This is a VSR11/Bar10 clone and therefore is very upgradable. The only problem with this rifle is the weak trigger sear, which is common in all VSR11/Bar10 clones. It is relatively easy to replace with an upgraded one. The standard sear should last a while though with moderate use. This rifle is very reliable, jams and misfires are very rare. It has excellent accuracy, especially when scoped. It is also powerful enough to be a very effective sniper rifle. The package comes with the rifle itself, a magazine, two slings (which doesn't really make sense), a sample bag of high quality bb's, an unjamming rod, and rails for a scope. I would definitely suggest getting a scope for it.
This is also a very common rifle used in conversions. I have used the base of this rifle to build a Mauser Kar98k, a Springfield M1903, and an Enfield P14. Very fun project for experienced and skilled airsoft techs.
*Power is just right to be used as both a standard rifle or a sniper rifle
*Sample bag of bb's is surprisingly high quality
*Has rails for both a scope and a bipod (sold separately)
*Overall great airsoft gun
*The only problem with this rifle is the weak trigger sear which needs to be upgraded to a steel one, or else the rifle will slamfire
