Complete Hop-Up and Inner Barrel Servicing

PRIMOREGGIMENTO.COM workshop service dedicated to complete servicing of the hop-up assembly and inner barrel of airsoft replicas.

Designed for customers wishing to replace a hop-up bucking, install a new inner barrel, restore a dirty or inefficient hop-up assembly, or improve accuracy and shot-to-shot consistency without servicing the replica's entire mechanical system.

The hop-up assembly and inner barrel play a fundamental role in shot grouping. Dirt, grease residue, worn buckings and poor component fit can affect performance even when the gearbox is functioning correctly.

Features and technical specifications

Workshop operations may include:

• Hop-up assembly and inner barrel disassembly
• Thorough cleaning of the hop-up chamber
• Inner barrel washing and inspection
• Removal of dirt and residue
• Inspection for burrs, defects and component wear
• Component fit and alignment checks
• Hop-up bucking replacement, when agreed
• Optional installation of a new inner barrel
• Correct reassembly and functional checks
• Standard consumables included: basic O-rings, small hardware and technical cleaning products

This service is particularly useful for:

• Inconsistent shot grouping or abnormal BB trajectories
• Poor or inconsistent hop-up adjustment
• Dry, worn or damaged hop-up buckings
• Dirty inner barrels or barrels requiring replacement
• Loss of accuracy compared with normal performance
• Replicas left unused for extended periods
• Installation of new hop-up components

Our workshop method

Whenever we replace a hop-up bucking, we also thoroughly clean the hop-up assembly and inner barrel. Installing a new bucking on dirty components would compromise the quality of the work.

When replacing an inner barrel, we normally replace the hop-up bucking as well, except in specific cases assessed individually. Pairing a new barrel with an old or deteriorated bucking could limit the improvement.

The process begins when the replica is brought to our store and an internal workshop job sheet is created. Work is not carried out by appointment; jobs are handled in order of arrival according to the workshop queue.

During the technical assessment, we inspect the components and determine the required work. A quotation is submitted to the customer for approval before proceeding.
