Sinclair F Class Bipod

I just purchased the above mentioned bipod and was curious as to what others are putting under theirs during matches or while shooting on rough or uneven ground. I shot a match this past Saturday with it attached. The grass was pretty tall where we were positioned so I positioned the bipod on the forward part of my mat but it still tracked unevenly. Any suggestions and information is welcome. Thanks for your help....

I own a couple of the Sinclairs and some clones. They work real well, especially the second design with the independant leg adjustments. I never put the bipod on the mat, just the ground for more consistent results. I also try not to move at all once I confirm natural point of aim and position, and then finalize adjustments of the rifle. I then bring the rifle back to the exact same position after each shot, including the bipod legs

John,

F-Class rules allow for a flat board under the bipod as long as it is not more than 2" wider than the bipod and no more than 12" deep. The attached image is mine. It is a 1X12, 21½" wide. I attached a handle to one side for carrying, counterbored and glued a Starrett bulls-eye level, applied two 6" wide UHMW strips for the bipod feet, and drilled three holes to locate my Farley rest when shooting F-Open. This was my prototype. I intended to paint the second one and make it look nice but the first one seems to work fine and I never got around to the second.

Scott,

Our shooting in the Southwest is typically on dry, sandy ground that quickly produces two ruts when not using a board or mat. One tournament at Phoenix shooting on the ground convinced me of my erroneous ways. Maybe the earth is a little firmer up your way. ;)
 
It may not be the best way but...........

I use a full-length mat. Up front I took a piece of very thinly-ribbed corduroy cloth from a fabric shop (approx 22"x10") and used couble-sided tape around the edges to secure it to the mat.

When I set up, I align it and "saw" the skids back and forth on the corduroy (running with the "grain") until they make a bit of a groove to slide in. Works great with a rear bag. Of course I don't have a pic of the mat...

I appreciate all the replies and ideas! I thought about taking one of the thin plastic cutting boards, maybe the wife won't miss it ;) and trimming it to the proper dimensions. I figured I'd put some outdoor carpet on the bottom to keep it from slipping on my mat and use the "slick" side up for the bipod feet to track on. Thanks again for the ideas, keep em coming.

John
 
I use a doormat with a soft rubber backing and "slick" synthetic unidirectional fibers on the working side, seems to work pretty well.
 
I had an old weapons carrier canvas case (buckle & strap, fold out type) that I cut one panel from and inserted a piece of 1/8" (?) sorbothane type material between the canvas and felt. Works great and then I use it folded up to protect the receiver barrel from the stock when I dis-assemble the Tubb to carry in case. Just an idea of what to use what is laying around.
 
Go to the grocery store and pick up a couple of the flexible cutting board 'sheets'. The Sinclair pod is wider than one, but you can couple them with three velcro dots along the edge. Mine are trimmed down so they fit in the side pocket of my range bag. I just pull them out and stick the edges together and put the gun on top - seems to work.

BTW... since these are flexible (you can roll 'em up in a circle), they are not considered a 'board or plate' per the NRA Referee @ the 2010 FCNC - so no worrying about dimensions.
 
This bi-pod is nice but needs an elevation adjustment in a big way. In F-TR, once you shoot the ele goes to hell and you have to move back and forth and back and forth and back and forth to get the ele right. Sinclare came came up with an ele adjustment but apparantly it is vapor ware. I know a guy that can make an ele adjustment so sweet you'd slapp your moma. I'm trying to get him to sell the idea but he is too causous on infringement rights.

And please, I know my spelling stinks....

I scored for Danny Biggs and his team at the SW LR Nationals in January. Danny shot the adjustable Sinclair in that match. It is still undergoing development and testing.

Otherwise, I agree completely with what you say about the standard Sinclair. It is solid as a rock but the "adjustment" is a cruel joke. If you cannot adjust the bipod height while sighting, it is almost worthless.

Tell your friend to get a patent attorney. Some will work reasonably with small entities to secure a patent.
 
I use the rear mat from my HHR it is the perfect size for my MWerks bipod.
It is not too stiff and the skids slide straight back.

I would get a Sinclair if it had the elevation adjustment, so +1 on what others have said. I contacted Sinclair a while ago, and they said it was coming out soon. That was more that 8 months ago. ???
I also asked MWerks to make something to fine adjust elevation. He said it was a good idea, but he never got back to me since.
Oh well. :P
 
Good Morning,

I have been looking at the Sinclair Bipod, and wondering if anyone has been shooting it free recoil. Now that the Benchresh season is over, I have been thinking about trying F-Class over the summer. Since I shoot free recoil off of the bench, I was just wondering if it would also work off of the ground using the Sinclair bipod.

F-Class Open & F/TR has to be shot from the shoulder per NRA Rules, NO FREE RECOIL.

I asked as well, back in January. The Sales Dept emailed back saying June/July at the earliest.

I can't see how making and selling an elevation adjustment block to work with it would tweak anyone's rights.
The details of Bigg's prototype are pretty easy to see from the photos. Just need some aluminum and a mill.
 
I shot Biggs's bipod gun in Phoenix this last January, that elevation adjustment is worthless if you can't reach it! My arms are too short!

A good point, Jerry. If you cannot use a control, it doesn't help. What we need is a lightweight co-ax head integrated into the bipod. It would not need a huge adjustment range, just enough to move around the target. Say, 5-6 MOA in any direction.

You know, I hadn't thought of that....still would be better than monkeying with the sides, though.
 
Just get a "caddy" and have them adjust it while you lay behind the rifle. Heck make them carry it to the line for you also.
