I got one from SG recently. Bore looks great! Same with the bolt and other moving parts. No sign of wear in them. But the finish is really well buffed off. Looks like it was carried as a duty weapon alot. The UF itself is shiny bare steel!
But it's good fodder for a project gun, so I don't mind.
My Pol UF from Copes looked much better. Same great bore.
I have a 90% (I hope!) Pol UF due here next week from the Ammunition store. Hope it's a good one. I got their $250 (Shipped) special with four mags, pouch, cleaning kit, sling, bayo, etc. They shipped it just three business days after I ordered. Not too bad.
