My husband has an at 15 and an ar 300 blackout(just built the 300 blackout) trying to find a mounted tactical light for one of them. I bought surefire M series scout light but I’m not sure if it’s good or not. I read reviews and it seems like surefire is always in the top 10. I just wanna give him the best on a budget of under $300. I would really love to surprise him and give him something he will love.
