  1. Check.out bg deffence I prefer both the rails i usually get, have m lock in the middle and picatinny full bottom and top but two inch on the front and one inch pic on the back
    Best of both worlds, and they feel great when shooting.

  2. New to guns. Owned firearms since April of 2022. However, I have lots of theory and not enough practice. I can easily sell being an expert on firearms, but I still consider myself a noob. I'm watching this video to learn more, especially since the ar15 I bought (model M15A4 by Armalite) has a free float smooth surface handguard. It's just for grabbing it with your hand and nothing more. Plus a super heavy 20-inch barrel I wanna get rid of. Over sized stock like the one on the M16 and a scope that I think is 3x magnification. It's horrible for indoor use if it ever comes down to it. So I am going to replace all of that.

  3. "At the end of the day they're just handguards" okay but what all companies make it without a full top rail? I've been using a BCA upper and prefer it over any other upper I've shot because it doesn't have a full rail on top and is easier for my infant hands to wrap around. What other companies making that style of upper?

  4. I need a drop in hand guard that has picatinny rails but goes further than the gas block, looking for something around 10 inches long, any suggestions, I don’t like hand guards that go most of the way of the barrel, I quite like seeing the barrel

  5. I’ve been running a pic rail drop in for over 30 years on my Bushmaster. I’ve never had a issue with it and since I run heavy barrels no shift in point of impact. Plus I can remove it without tools for cleaning oiling the barrel. But if you run a bunch of lights lasers or kitchen sink then the free float is probably for you.

  6. I can get my handguard off no problem. Its the typical plastic 2 piece guard. I measured it and its 6inches. Directly in front of it is that giant front site piece. The issue is most of the aftermarket guards im seeing are 10.5in or longer. How can I make it fit?
