Details, This is one unique pistol (so far!). The new WE Double-Barrel Glock 17 features quite a few new proprietary parts including: a double barrel slide, double hammer assembly, double-size magazine housing, double lower frame, individually adjustable hop ups, Glock double magazine/baseplate and double barrel bushings. WE has strived to keep as many parts as possible interchangeable with their standard WE single Glock counterparts, so you will also be pleased to find that many parts are cross-compatible between single and double Glocks. The dual magazine holds 50 bbs (25 in each side), so you get 25 shots from a full mag. This has a very heavy kick, is very snappy and great fun to shoot! You MUST be 18 or over to purchase this. Please note this is a VCRA applicable Realistic Imitation Firearm. You must be UKARA registered (or have a defence under the VCRA) to purchase this as is, Please contact us or state your UKARA registration number in the comments box when you order. If needed we can spray this for you (at an extra cost of £10.00) so that it meets the requirements to allow anyone over 18 to purchase this. Please select this option from the menu above.
