Smooth Operator...
I called to cancel the JP spring after discovering the gravel sound was coming from an expensive 7075 buffer tube and not the spring. I Replaced the tube with a temporary from the junk box and things smoothed out and quieted up. I was too late calling to cancel the order and the JP Spring arrived today. Well I am glad the order did not cancel because charging is more smooth operating and more quiet. It's definitely a keeper.
No more springy twang!
This spring eliminates the springy twang noise I used to hear when shooting my carbine with the stock mil-spec spring. It also tamed the excessive cycling rate experienced when running the gun suppressed. Highly recommend for every AR.
Better than milspec!
Its not the silent captured spring JP makes, but it is still one heck of an improvement over any milspec buffer spring. It is quieter and smoother than the standard springs and well worth the money. I still prefer the silent captured spring system if running a suppressor but for a tenth of the price this one works very well!
Really Good Spring
This a really nicely made spring. I coupled this with a Noveske rifle buffer and my rifle is a smoother shooter for sure. Its a nice affordable upgrade that makes a noticeable difference in my rifle cycling.
Great Spring
This a really nicely made spring. I coupled this with a Primary Weapons H2 carbine buffer and my rifle is a smoother shooter for sure. Its a nice affordable upgrade that makes a noticeable difference in my rifle cycling.
IT WORKS!
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!
Quiet
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!
These work
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.
