SA TDC Magnus™ AK Hop-Unit Unit and Helium™ Flat Bucking - Black

Specna Arms TDC Magnus™ AK Chamber

Want to increase the accuracy of your AEG AK? Looking for a chamber that provides stronger and more stable pressure even with heavy BBs? Want to eliminate side-curving shots and gain consistent backspin? The TDC Magnus™ hop-up chamber equipped with the Helium™ Flat bucking is exactly what your rifle needs. TDC pressure works vertically and directly above the barrel window, eliminating inaccuracies of common lever systems. The Flat bucking, thanks to its smooth internal surface, offers a wider contact zone, resulting in stronger rotation, longer range and excellent accuracy.
