Grabbed some xrf's the other day as its that time a month and i need em for inspection. Figgured id do it once and do it right so i bought these. They were supposed to be all sealed, and turns out uppers are not. So i called the ppl, and asked what up. I was told XRF made another change, and now their back to greaseable uppers? Anybody have any input on this, or on whats really better grease or no grease... ?? I was under impression, they recently swithed to sealed. Now im confused:confused013:
