Airtech Studios ARA Advance R-Hop Arm

Airtech Studios
  • No Modification
  • For R-Hopped Guns
  • Even Bucking Contact

R-Hopping is the latest popular HOP modification for Airsoft Guns, which involves using a Flat Contact Patch on the bucking to impart perfectly even backspin on your BBs, even if imperfections are present in the BB. This style of HOP Modification usually requires a modified HOP Arm, which can lead to imperfections if the modification is not carried out perfectly. This HOP Arm is ready to drop in to any R-Hopped system and apply perfect and even pressure on the contact patch, allowing you to make the most of your upgrades. Not only this, but it will work with standard HOP Units, stopping you having to spend money on aftermarket units.

Parts Fitting

Upgrades and Downgrades should only be undertaken by experienced players, or Airsoft Technicians. Please note, changing any internal parts of a weapon voids its warranty unless done in-house by our staff. 

Please ensure that when fitting parts the part purchased is the correct part, as once a part has been fitted we cannot accept return.

We do know that players love to tinker, so we're here to give you help should you require it, and if needed you can get in touch with our workshop for more help!

Unique Parts

Please note that some parts may be unique to a specific brand of weapon. For example: Parts for an ASG M4A1 may not fit an ICS M4A1.

Parts from the same brand typically have a high chance of fitting, though be warned, some replicas use unique parts, so please ensure the part will fit before you attempt to fit it.

If you require help with fitting any parts feel free to get in touch with us via our Contact Us Page.
