Upgrades
There are many upgrades available for the ProMaster. One upgrade that must be bought immediately is a bottom line setup, the most popular of these being an on/off valve style ASA (Air Source Adaptor) with a macroline hose. Any 45 style grips will fit it and all Autococker/Intimidator barrels will work as well. The feedneck is threaded into the body and can be replaced with any Bushmaster-style feed neck, such as the feednecks manufactured by AKALMP, CCM and ICDU. Another very popular upgrade among ProMaster users is the Indian Creek Designs Underground Cylinder Assembly. It consists of a new cylinder and ram unit as well as a Quick Exhaust Valve, or QEV and hose barb. The low pressure regulator pressure can be dropped significantly after this upgrade. This increases the ProMaster's air efficiency and cycle speed as well as reducing the amount of recoil felt when firing. Another advantage to adding the ICDU cylinder is the hammer can be removed out of the back of the gun, resulting in an easier maintenance process for the user. Other popular upgrades are replacement high pressure regulators, low pressure regulators and valves that offer higher air flow and consistency, resulting in higher paintball velocities at lower air pressures, thus increasing the ProMaster's efficiency. Aftermarket Micro-processor circuit boards are available from NOX, Kila Products and Vaporworks. The ProMaster shares the same circuit board type as the newer ICD Freestyles. Yet another popular upgrade is widely available on www.ebay.com. It is a delrin bolt link pin, which links the bolt to the ram hammer. It is very popular because it is light in weight, prevents scratching of the body and, is very inexpensive compared to most other upgrades available for the ProMaster. Delrin bolts are also available, however the stock bolt has proven to be a strong point of the gun because it is also made of delrin and no evidence of performance gains has been shown with the use of an upgraded bolt. New high flow solenoid valves are also available from ICDU website as well as Airsoldier.com
