Proper recoil spring diagnosis?

[michaelmew]

Your buffer is too light to start, not the whole problem but it may be a cumulative one.

Your buffer should ideally weigh as much as a rifle buffer, it increases dwell time and softens recoil, all kinds of good stuff.

Try a Spike's Tactical Heavy Buffer. http://www.spikestactical.com/new/z/lowe...p-201.html I recently switched and have had good results. I am planning on using them in all my AR's
