Well I have taken the plunge into long guns. First rifle purchased. Now I have to personalize it. S&W M&P15-22. I am waiting on two 35 round mags, magpul mbus sights, magpul pts angled foregrip, and larue handguard clips. I do want a scope/red dot/holo, which ever one is best for the money. Going to be a while because I just spent some cash on the other parts and have to make up for it. But anyone have any suggestions on optics. I want to be able to shoot a pretty long distance with it. And what is it the hinge that allows you to move the scope of to the side and back on top by swinging it. That looked cool. Thanks.
