Does anyone know what this is? It is sa marked, appears to be some sort of threaded adapter but I have no idea what the use would be

It's a Civil Guard muzzle cover fro m/28 rifle. Finnish Defence Forces later marked it with [SA].

Thanks, it is on an m28 that someone is selling as a "competition/sniper mosin". It has that barrel cover and windage adjustable rear sight, bent bolt. I am assuming the bolt was bubba because there doesn't appear to be a recess cut in the stock like the cavalry rifle. I was hoping I found something rare
