SR4 RIS PROLINE AIRSOFT GUN
This new hybrid airsoft gun is from Bulldog Airsoft, it is something completely new and exclusive to Just BB Guns. It has the externals of a sportline gun but the internals of a Gen 3 airsoft gun. You will not find this winning combination from any other brand of airsoft gun. So let’s break it down – full-size polymer and ABS RIS M4 frame and external parts. SRC generation 3 metal gearbox with 8mm bearings, steel gear set, ultra-high took motor, aluminium spring guide and aluminium bearing piston head. This makes this gun built to last, and you can feel the difference of the upgraded internals when you have it in your hands. The M4 RIS features a long 20mm weaver rail along the top to fit all major scopes and red dot sights or the supplied cut-down rear sight. The front handguard system will also give you as much accessory space as you need from front drop-down grip to lasers and torches. If you are looking for an airsoft gun that is built to last without breaking the bank, this is the one for you.

WHAT IS A HOP-UP
A hop-up device applies a backspin to the projectile reducing the air pressure on its top side. This causes the plastic BB pellet to fall less over a given distance than it would without the spin applied, extending the effective range of the weapon without increasing velocity. This improves your accuracy and increases your shooting enjoyment both down range to a target or in an airsoft battle.
HOP-UP ADJUSTMENT
- Pull the charging handle to the rear, exposing the hop-up dial.
- To reduce the hop-up, rotate the hop-up dial towards the normal setting.
- To increase the hop-up, rotate the hop-up dial towards the hop setting.
- This gun has a rotary hop-up with 20 positions for fine-tuning.
