Advanced TDC BB Tube (Silverback A1/A2 & Maxx Model | Maple Leaf Hop-up Chamber)

The Advanced BB Loader is designed to address the misalignment issue by the stock feeder. Our new BB feeder is designed specifically for the Silverback SRS A1/A2 and paired either with the Maxx and Maple Leaf Hop-up Chamber unit.

On the current SRS during installation, you will notice that the hop-up chamber / outer barrel can freely twist round easily around the BB feeder, which leaves a degree of guessing and approximating for the true center before locking the 4 screws. If it is not fully centered, this can lead to BBs swerving away to the left or right.

We address these issues by designing the feeding lips to be slightly longer and flatter than the stock BB feeder to act as a "guide rail" for the hop-up units to be completely centered upon installation. 

The new BB feeder will ensure a snug fit with the hop-up chamber until the outer barrel is locked onto the SRS rifle eliminating any doubt or guesswork on where the true center lies. Simply slide in and lock.

✔ Prevents Lateral and Axial Movement of the Hop-up Unit Before Installation.

✔ Guarantees a ‘Dead-Centre’ Chamber Lock on the true vertical axis.

✔ Eliminate Guess-work Before Locking the Outer Barrel after Maintenance.

✔ Guides the Outer Barrel into BB Feeder Ensuring Zero Tilt

✔ Tough CNC Stainless Steel Construction

✔ Quicker Assembly Time. Simply Slide in the Hop-up and Lock the Bolts!

Due to the nature of disassembling your SRS Silverback rifle often for maintenance and cleaning for the best performance. It is essential to retain all factors during install to remain constant. This BB feeder will eliminate one crucial element to ensure your settings remain the same every time.
