Detailed Description


The Wilson Combat AR9 Optimized Recoil System allows the user to adjust action spring weights to tune their bolts cyclic rate for optimum reliability.  This drop-in system is compatible with the Wilson Combat AR9 and similar short-stroke, blowback 9mm AR carbines.

The AR9 Optimized Recoil System comes with three full-size 1911 recoil springs (recoil spring weights 15, 17, and 20 pounds)  to tune your bolt’s speed to optimum reliability. 

This buffered system will reduce wear and tear on your AR9 and provide you with a softer recoil impulse for faster follow-up shots and is ideal when tuning your gun for competition use.

Produced of high-quality, fully hardened stainless steel with no pins or fasteners to fail, the Optimized Recoil System will stand up to years of hard use. The black polymer buffer cushions the action for smoother shooting. (Replace buffers when they become worn or damaged. Extra buffer included.) Comes with 3 recoil springs included to tune to ideal reliability.

  • High-quality stainless steel construction, drop-in fit
  • Tuneable to your specific ammunition
  • Smoother feel without the grating sound of a standard action spring
  • Three recoil springs (15,17, 20 pound weights) included to tune your gun for your specific load - Need to replace your worn or damaged spring - Click here for 15#, 17#, & 20#.
  • Black polymer buffer cushions the action 2 included.  Use 1 now, then replace when buffer is worn or damaged.


To Install the AR9 Optimized Recoil System

  1. Remove the standard buffer/action spring system and ensure that your buffer tube is clean and free of dents.
  2. Lightly lubricate metal parts of the Optimized Recoil Buffer System with the oil of your choice
  3. Install rear buffer section in the buffer tube followed by the spring-loaded buffer assembly just like a standard AR buffer
  4. Reassemble AR9 and hand cycle to ensure you have adequate bolt travel
  5. Testfire your AR9 to ensure reliable lockback and function
  6. Replace black poly buffer when it becomes swollen or torn


Note: We recommend using the heaviest recoil spring that will fully cycle your ammunition and lock back on empty.
