Great Product


The buffer kit does exactly what it is supposed to do. The finish is great and the kit installed great on my YHM lower.

better than expected!


The price on this product was great so I expected an average product... Wrong. The quality and feel is the same or better than a couple units I paid more for. Excellent purchase and thank you primary arms for incredible service.
