I picked up a new SIG 522 Commando the day after Christmas...the gun looks & feels Awsome in hand but I might be sending it back to SIG to check it out

I took it out of the box ran a boresnake downt the barrel a few times, loaded the 25rd mag & went to shoot....EVERY SINGLE ROUND STOVEPIPED ! The bullets loaded into the chamber & shot fine but when the bolt went to cycle another round, the empty brass would stove pipe

I posted this on SIG's forum & everyone has told me that I neede to field strip the gun & Lube everyting that they ship pretty dry & that this should fix it...I done this but haven't had any "Range Time" to find out.....just upsets me that I paid $500 for a .22LR that won't cycle properly

Everyone that I've talked to that has these told me that they have never had a single jam & was shocked at how mine has done....Here is the model I have
