Re: Bipod, Atlas VS Sinclair varmint.
Well, I did get my Sinclair bipod a couple of days ago. I have not had the chance to actually get in any shooting with it though. I did however mount it on my f-class rifle and play around with it some. My first impression of this bipod is that it is well made, I will state at this point the only other bipod I have owned are those made by Harris.
The Sinclair bipod is a bit heavy weighing in at 1 lb. 12 oz., but that weight is due to its sturdy build. All of the tolerances on the Sinclair are what you would expect from a $230 bipod, however there is some slight movement in the legs when you have the bipod in shooting position. I realize that for a bipod to be useable in different environments, there has to be a little for it to perform properly. I usually "push" my gun slightly forward when preparing to shoot and that bit of movement, I hope will not be noticeable.
Each leg is independently adjustable, as you would expect. The extensions have positive stop locks that you push to release. To deploy the legs into shooting position there is a knurled pivot release on the side of each leg that you must push to rotate the legs down. This knurled release must also be pushed to rotate the legs back up into the carry position. While on the subject of this knurled release, if you push it and pull out on the leg, you can actually remove the leg from the unit. I'm not sure if this is a pro or con.
This bipod has what is a very innovative concept, in that each leg has a narrow position and a wide one. In the narrow position the bipod has an adjustment range of 9.5" to 12.5" To go lower than the 9.5" height, there are spring loaded pull pins located near the pivot point of each leg. Just pull this pin and rotate the leg out to the wide position. In this wide position the bipod has an adjustment range of 6" to 7.5", for adjustment ranges between 7.5" and 9.5" you can leave one leg in the narrow position and spread the other leg out to the wide position. Since this bipod has lockable rifle canting, you can get your rifle level and locked in position in seconds.
The only complaint I have about the bipod is the size of the pin trigger on the right side of the bipod. This pin trigger is what actually attaches the bipod to the stock via the swivel stud. This pin trigger sticks out 1.25", it looks like there could be room for something less protrusive, but that just my opinion.
Overall, I believe I will find this bipod very user friendly. I hope to get the chance to get in a little range time this week and put final approval on this bipod. I will try to update when I do....
