    works as intended
    PS the 5 star review is also left for ASTONASHING customer service and speedy shipping

    So glad I swapped my carbine tubes for this A5 (wagyu). It’s a Recoil Delete cheat code. Run the same buffer weight you run in a carbine. I honestly don’t know why Carbine receiver extentions are still a thing.

    So many adjustments. Great fit and finish and paired perfectly with a Springco and VLTOR buffer. The only thing nicer than my new A5 setup was the free meal from Rooftop.

    These are the same tubes as the FCD 9 pos tubes with different brand markings. Very high quality fit and finish! I pair them with a5 buffers and G 42 rifle length springs. Shoots flat!

    Killer price on the a5 kit. I will say after buying two solgw buffer tubes, on the next one I will buy a solgw end plate for under the castle nut. I know the three endplates I had on hand were cheap parts and take offs so I had to file the edges and tab to fit. I bet the sons end plate will slide right on.

    Can’t wait to see what this a5 setup is all about.
