Buffer tube for magpul prs lite stock

[Troy fairweather]

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.

Thanks for some info, what mount height are you using with the magpul prs lite even with the comb down it's seems higher the say a A2 stock. I believe the lite stock needs a mil spec buffer tube, guys using the aero has some fit issues.
