Important Notice for the Purchase and Delivery of Airguns, Pressure Components of Airguns, and Moderators

 

Effective Compliance with the Violent Crime Reduction Act 2006 (VCRA): Sections 31 and 32

 

Under the provisions of Sections 31 and 32 of the Violent Crime Reduction Act 2006, which were enacted through "The Violent Crime Reduction Act 2006 (Commencement No 3) Order 2007: firearms measures," specific regulations now apply to air weapons, their Pressure-Bearing component parts, and certain accessories.

 

Key Points to Note:

Restricted Items:

  • Airguns: All airguns are classified as restricted items.
  • Pressure-Bearing Parts of Airguns: This includes barrels, cylinders, reservoirs, and pistons.
  • Functional Moderators (Silencers/Suppressors): Moderators that reduce the sound of discharge are also classified as restricted items.

 

Definition and Registration:

  • Component Parts: While the VCRA does not explicitly define "component parts," the Home Office interprets this to include pressure-bearing parts such as barrels, cylinders, reservoirs, and pistons.
  • Accessories: Only moderators (silencers) require registration by dealers.

 

Legal Requirements for Transfer:

  • In-Person Transfer: It is an offence under the VCRA to transfer these restricted items through standard postal systems or to the end customer directly without the presence of both the buyer and either the seller or a representative of the seller.
  • Representatives of the Seller: This can be:
  1. An employee of the seller who is a registered firearms dealer (RFD).
  2. Another RFD authorized by the seller.
  3. An employee of the authorized RFD.

 

Collection and Delivery Options:

  • Collection from Store: Customers are encouraged to collect their restricted items directly from the store where purchased.
  • Transfer to Another RFD: Items can be transferred to a local RFD for collection, though the receiving RFD may charge a fee for this service.
  • Home Delivery: We offer home delivery through our in-house team to some areas of the UK. However, please note that this service has location restrictions and incurs higher costs due to the need for dedicated transport, making it more expensive than a standard RFD transfer.
