Question: does this come with an adapter for a rail some answers say yes some say no
Document: Harris only offers their bipods with a sling mount, which does require you to buy an adapter if your rifle has a rail on it. The adapters run from $5 to $30 depending on the brand and quality. Read the review on those, some people have had problems with the sling mount being too long, which will prevent the bipods mounting system to fully tighten down enough to hold the bipod tight to the rifle.
Bi-pod was exactly what I was looking for;  mounts easy enough onto my AR 15;  seems to be high quality, have not had it out to the range yet. Kind of dumb though that this product is sold as easily mounted on a piticanny rail when in fact there is a mounting adapter that you have to purchase separately. Once installed bi-pod adjusts easily to a variety of heights.
This is a nicely made product. It is sturdy, stable, and lightweight. It would be very hard to improve on this design. With one teensy exception. Message to Harris; there are a large number of people mounting these on picatinny rails. I wouldn't be surprised if it there where more mounting to firearms that way, than by a sling mounting pin. How about a version that mounts directly to a pic rail without the expense, weight, and extra hassles of an adapter?
I didn't think I needed a Bipod on my AR15 build but was I wrong. After shooting  a few times using sandbags or holding the AR in my hands I got the message. My accuracy went up a few thousand points and I can actually sight my scope using the bipod. Its too bad that the rail adapter sells separately but this Bipod is well made and will last as long as your rifle. Highly recommended.
This bipod is very solid and lighter than one would expect when looking at it. My main complaint with this product is with the screw that tightens the clamp which holds the device to a rail adapter. It is on the short side which depending on the rail adapter you choose could cause you to make some engineering changes. I modified the adapter instead of this bi-pod but a longer screw or longer grip teeth on said bi-pod would have made this modification unneeded and the bi-pod more secure.
This paired with the Harris RotaPod is roughly 1lb. I would say.
Let's just say me and a friend went to the range and quite a while later he commented on how much he noticed the quality of my bipod vs. his cheapy &#34;made in China&#34; version. That means it must've made an impact!It's a very sturdy piece and will likely only turn to Harris for future builds.
Harris bipod Works great going 2 order an other 1. Put several rounds through hasn't loosened up. Adapter is also good.
Does exactly what I expected it to do. Installed it on my DPMS LR 308 in less than a minute with no tools and no adapter required. Rock solid as any Harris bipod should be.
I've tried the cheaper brands but always come back to Harris BiPods. These units are easy to instal and function beautifully. Legs move easily into position and stay that way. Folds into a nice compact package and there is less noise and rattle than you get with cheaper units. Nice size for bench or prone shooting. Overall this is a very fine product.
Answer: yes
