JP Ground & Polished Buffer Spring - AR-10 Rifle
Recommended for 9mm AR with 14.5 - 16" 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.
For 9mm ARs these AR-10 rifle springs are recommended for 14.5 - 16" barrels if using our 9mm Hydraulic Buffer. They give the most spring force possible and this helps to decelerate the heavy 9mm bolt before it impacts at the rear of it's recoil stroke. This helps in holding bolt in battery, keeping recoil to an absolute minimum and reducing wear on trigger parts. This spring is too long for our Aktive buffer or any typical AR carbine buffer. They also work great in any .308 AR-10 with a fixed stock. Expected service life is 10,000-20,000 rounds.
