Specna Arms TDC Magnus™ M4 Chamber

Want to increase the accuracy of your AEG M4? Looking for a chamber that provides a stronger and more stable pressure even with heavier BBs? Trying to eliminate the issue of curving shots and get consistent backspin? The TDC Magnus™ hop-up chamber paired with the Helium™ Flat bucking is exactly what your rifle needs. TDC pressure acts vertically and directly above the barrel window, removing inaccuracies typical of standard lever-based systems. The Flat bucking, thanks to its smooth internal surface, ensures a wider contact patch, stronger backspin, longer range and excellent accuracy.
