Its specially shaped single-point contact patch is designed to centre the BB and produce a straight, repeatable axis of spin.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eThe Friction Pro combines a relatively small contact area with a carefully shaped friction patch. The design reduces the possibility of uneven contact while still providing enough grip to effectively hop heavy BBs up to 0.48 g in a suitable setup.\u003c\/p\u003e\n\n\u003ch3\u003eConsistent and centred backspin\u003c\/h3\u003e\n\n\u003cp\u003eThe shape of the contact patch is designed to apply pressure to the BB as centrally as possible. A centred axis of rotation helps reduce unwanted side spin and supports a flatter, more predictable trajectory from shot to shot.\u003c\/p\u003e\n\n\u003cp\u003eInstead of maximising the size of the contact surface, 4UAD has focused on providing the required friction through the shape of the patch. This helps combine strong hop performance with consistent BB positioning.\u003c\/p\u003e\n\n\u003ch3\u003eSuitable for heavy BBs\u003c\/h3\u003e\n\n\u003cp\u003eThe Friction Pro is rated for BB weights up to 0.48 g, although the maximum usable BB weight always depends on the complete hop-up system, hop-up arm, chamber and replica.

Instead of simply holding the barrel in place from one direction, the tri-lug design centres it inside the chamber while locking it firmly against unwanted movement.\u003c\/p\u003e\n\n\u003cp\u003eA precisely machined CNC bucking sleeve also supports the hop-up bucking, helping maintain its correct orientation and preventing it from twisting or shifting during use.\u003c\/p\u003e\n\n\u003ch3\u003eEasy adjustment through the ejection port\u003c\/h3\u003e\n\n\u003cp\u003eThe Magnus Pro adjustment dial can be accessed directly through the replica's ejection port.
