Product Information

4UANTUM MAGNUS PRO TDC Hop Chamber - VFC GHK AR GBB

Precision machined from solid 6061 aluminium billet, The MagnusPro Hop-Up chamber features a true vertical TDC (Top-Dead-Centre) movement. This means regardless of your hop-up setting, the pressure point remains in the same position for consistent results. Revolutionary self-centring tri-lug locking is the most effective design at not only centring the inner barrel but also holding it firmly in place! CNC bucking sleeve precisely centres the orientation of hop-up bucks and keep it in place for lasting accuracy. The adjustment dial is easily accessed through the ejection port & can be adjusted with any pointed tool without the need for disassembly, allowing efficient & streamlined hop-up tuning.

Remark:

• GHK AR GBB system: Install without the included spacer.

• VFC AR GBB system: Install with the included spacer.

Fitting & Returns

Replicas vary between makers and production batches, so a part can sometimes need work to fit. If you're not confident fitting it yourself, we recommend using an airsoft tech. Not sure a part suits your replica? Email info@ebog-designs.co.uk before you order.

Unfitted, unmarked parts in their original packaging can be returned for a full refund if you ask within 30 days of receiving them. Fitted or altered parts usually can too, less a deduction for any loss in value. Made-to-order items and gift cards have different return rules.

If a part is faulty, not as described or not what you ordered, there's no deduction, even if you've fitted it. Damage from incorrect fitting after delivery isn't a fault, unless it was caused by wrong or incomplete instructions, whether they came with the part or from us. Full details are in our Refund Policy.

Upgrade parts are sold for use within the legal power limits that apply where you are.

Finishes can vary slightly between batches, and colours can look different on screen.

None of this affects your statutory rights.
