JP Ground & Polished Buffer Spring - AR-15 CarbineRecommended for 9mm AR with 4 - 6" barrel
JP Enterprises Extra Power Buffer Springs are center-less ground and polished to a mirror finish on the outside edge for silent, smooth operation. These springs run very smoothly and much more quietly than standard buffer springs. Great for those tired of the raspy sound of AR buffer springs and for those using suppressors. These combined with our 9mm hydraulic buffer reduce spring noise significantly. These springs are 7% extra power compared to a standard weight AR-15 carbine buffer spring. They are equal in power to the Sprinco Blue spring.
In 9mm AR-15s these are recommended for 4 - 6" barrels if using our 9mm Hydraulic Buffer or 4-10" barrels if using our 9mm AKTIVE Buffer. They are fantastic in any .223 AR-15 with a collapsible stock. Expected service life is 10,000-20,000 rounds.
