Multi Spring System

Special buffer system as an upgrade for all AR15 Carbine Buffers including MR223. The use of two locking fields in series results in a particularly soft
soft spring rate of the buffer system is achieved. In practice, this means a greater spring force when the bolt is closed in order to be able to feed and lock more reliably without increasing the required maximum loading force.

Furthermore, two extra spring sets are included in the set to enable optimum adjustment to the ammunition, weapon and any silencers used. The extra spring sets are about 20% stronger or weaker than the standard spring set.
Made from high quality stainless steel.
