IT WORKS!(28/04/2017)
Built an AR308 with a standard 308 carbine buffer spring in a Magpul CTR stock. Would only lock back the bolt carrier about 50% of the time after the last round. Installed this spring and now get lock back after the last round 100%. Used a standard 3.7oz buffer both times. Problem solved!
308 Rifle Flat-Wire Buffer Spring(22/03/2014)
I replaced the factory round buffer spring in a new Remington R-25, 7MM-08 with this buffer spring because of multiple feeding and extraction problems. I fired 100 rounds, fast and slow, without any malfunctions what-so-ever.
Excellent Product(20/02/2012)
In Canada, we can buy Norinco AR's. Although well built, the finer points are missed. One of those is final fit/finish/quality on some things. Gun worked great, but adding this, smooth consistent cycling, and the brass all went in the same area. It did minimize the buffer tube noise as well.
No more ringing sound at all - amazing(03/04/2012)
Installed this spring with a tiny bit of grease for lubrication, and it works amazing. Just as promised. Gun feels nice and solid when I shoot it, and I don't feel or hear any of the spring action anymore. I ran this with a spikes heavy buffer.
Nice!(18/11/2013)
I've used this spring in multiple carbine builds and a pistol; both in conjunction with standard, H2 and Spike's T2 buffers. Never had any issue with cycling. A top quality upgrade.
Great part(26/03/2015)
Great product, great price. Highly recommended.
Works well, but short life.(16/07/2018)
Very nice part, but low life expectancy. Did not see anything on JP's site or anyone mention on here, but on the card I got with the spring the recommended replacement is only 5,000 rds. I don't consider my self to shoot much, but 5k rds comes quick and was disappointed to see that after I got it. That said it works very comparably to the flat springs I have and have yet to hear any spring noise when firing.
Great Spring(04/04/2012)
I use this spring with the AR-Restor buffer. It has tamed my .50 Beowulf more than I thought possible!
Great buy(04/02/2014)
Excellent spring, takes alot of the "chung" out of the action. The extra power of this spring really drives the bolt home.
These work(31/01/2016)
Have used these springs in my own rifles, installed in customers rifles, never had a complaint. Just ordered a couple more to have them in stock.
Quiet (24/08/2016)
I have liked shooting AR's, but always hated the "boing" and rattle. When I built my own, I decided to eliminate those noises. Between the Spikes Tactical tungsten buffer and a JP Enterprises tuned spring, the only mechanical noise is from the bolt movement. Pure joy!
