Does your FRT not run right?

If you threw an FRT into your AR and it doesn't run right you probably need these! For sale are two tungsten buffer weights. If you throw these in your carbine buffer replacing the steel and or aluminum weights, your rifle will be able to keep up with the FRT. These will also work if you purchased a suppressor and your AR is overgassed or if you built a short 11.5 pistol. Price is $60 for both weights.
