    Of those two - do both use the special long buffer and standard rifle spring?

    How much, if any, additional travel is there in the buffer from full recoil to the bolt being closed?

    From these photos, it would appear that the A5 has the same amount of travel as a standard carbine stock, but is designed to work with a rifle spring. Is that the case?

    They are the same length, the one designed for the Emod stock has an extra locking position.

    Both use the A5 buffer and standard rifle spring. The A5 RE and buffer are extended the same length, so bolt travel remains the same as carbine.

    May I ask why? What are the benefits, etc? Why not mid or carbine length? Thanks

    16" carbine gas 300BLK here. I have not had a single hiccup in this rifle. Vltor A5 kit should be here Friday, it should be just about perfect then.

    I wouldn't go Pistol gas unless it is to be suppressed or a SBR/Pistol.

    I am hearing great thing about the 12.5" barrel and the longer suppressors, shortcoming is no IR LASER with the dual BDC ability.

    Sounds like 200 yards with subs and 500 yards with supers.

    With carbine length buffers.
