Spring guide Krytac or Retro MG CUSTOM

The power regulation system patented by MGCUSTOM. It has meant, once again, a revolution for all players who incorporate this fundamental element in their AEG. It is not only that the spring guide can be quickly extracted, but it can also be compressed and decompressed by regulating the spring preload, thus adjusting the power, fps to fps from the outside without removing the spring or the gearbox. This system incorporates two elements, one of them made of 7075 aerospace aluminum and the other of them in self-lubricating brass. In addition, it incorporates ball bearings perfectly aligned to relieve tension to the spring, so the power will be much more stable and for much longer. The best example of use of this guide is; in which you are losing power over time and thanks to our adjustable spring guide you can keep the power always at the limit, on the other hand, at some point it may happen that our replica has not passed the test of time for very little, with this guide, in less than 2 minutes you can lower the power of your AEG to play anywhere, anytime and any environment and any situation.
