So I just got a brand new Saiga 12 its my first one and I have what I beieve to be a small problem. The gun came with a cheap plastic thread protector on the barrel, I was out shooting today ran some rounds and looked at the end and it was missing. I looked down range to find it with no avail, so I came home and promptly ordered a new steel one from Tapco. Here's the question..is it going to damage the gun in any way if I shoot without it until it arrives?(About a week shipping)
