|These are very good rails, and work great on a MOE type forearm for an AR. So far, I've only used mine for holding a flashlight at both the 10 o'clock and 2 o'clock positions, which it does well.
I nearly gave this 5 bullets, but as I have not used it for holding vertical foregrips yet, and haven't used on a wide range of other attachments, I didn't want to promise something I had yet to try out. If you're going to buy a MOE forearm, you might as well buy one or two of these as well to add the flexibility. It could be a 5 bullet purchase if you consider the value for the $.|
