Repairs Builds and Upgrades

At Dave’s Custom Airsoft LTD we are extremely fortunate to have built up an incredible reputation for quality work over the last 10 years. We are an AEG specialist, but we also take on Gas Blowback Rifle and Pistol repair and upgrades. In terms of the price range, we work on any replicas from £100 Rifles to the £6,300 HK11/21 we made for a customer in the Czech Republic. We do not currently offer internal tech work on Bolt action sniper rifles. 

Our turnaround times are some of the fastest in the business and vary between 1 and 3 weeks total depending on parts availability and how busy we are at that time. Our highly experienced technical staff are on hand Monday to Saturday 10 am to 6 pm to assist you and we work on literally thousands of replicas every year.

Replicas on our website can be purchased with a great many custom options and of course, we alternate between completing custom work on new orders and ensuring we complete jobs bought into us from customers in a timely manner. When considering how to get your weapon to us you can bring the weapon to our showroom/workshop at Unit K The Factory, Crondall Lane, Farnham, Surrey, GU105DW between 10 am to 6 pm, Monday to Saturday, or, having agreed on works with us remotely you can post your replica via the allowable Parcel Force Service to the same address above ensuring you include a cover letter with your contact details and a brief description of the works you want to be done. Finally, we can also have Courier collect and return your weapon/s for £25.00 in total (1-way shipping is £14.00).

With all tech work, you have the option to supply your own parts if you wish or we can supply parts by our suggestion or at your request. The tech will call you before starting the work to ensure we are fully clear with what is required, the tech will call you again once the gun has been opened to discuss what we find internally, and finally, the tech will call you once the works are complete, supply you with an invoice and take payment. The invoice will be dated, and your warranty period of 6 months will start from the date on this invoice. AEG customers beware that our warranty only covers 7.4v Lipo Batteries or equivalents, the use of an 11.1v Lipo for replicas that require it will require our consent. Any attempts to disassemble your replica will also void the warranty. If you find any issues whatsoever after work, please ensure you contact us, we will help you to fix it remotely where possible or we will arrange to have the weapon returned to us for remedial works.

Our standard labour charge for AEG tech work is £30 per hour, or £150 fixed labour charge for complete disassembly, installation of any upgrade or replacement parts and reassembly of an AEG. The fixed charge rates are often the most sensible as it prevents large labour bills should we encounter any snags or difficulties with your weapon whilst working on it.

To arrange a custom build, repairs or upgrades, please complete the below form called 'DCA Job Acceptance Form' and post your weapon with the form to the below address. We will then take a look over the work requested and get back to you with any comments. Alternatively, you can drop off your weapon in-store and we will be happy to talk with you about the work and upgrades you require. Please ensure you also read & understand the terms & conditions listed below.
