Buffer tube for magpul prs lite stock

[grayfox]

I have the PRS lite and like it. Using carbine buffer tubes. Matter of fact I have 2 of them but one is on 18" 223 wylde, 1 on 18" 6Arc. I'm currently experimenting with buffer wts, the Arc will wind up most likely H1 or H2 - the Spikes T2 or Kaw valley since I already have them in hand. The wylde uses regular carbine buffer.
Mostly I run MBA-3's but these 2 are the PRS/lt.
