Bipod Bounce

3312 Views 11 Replies 11 Participants Last post by  m14dan
I just finished drilling a hole in the Springfield Armory synthetic stock for the stud to attach the Harris bipod . I think mine extends from 9 to 13 inches . Don't really know why i drilled the hole for the stud as i've never had much luck shooting off a bipod .

I've tried it on many rifles in many positions with the same results . Vertical stringing . I've tried it on a bench , tried it prone and tried it on hard surfaces and padded surfaces . The results are always the same . Vertical stringing .

Shooting over everything from sandbags to rucksacks and it works out just fine .

Anyone else experience , bipod bounce and vertical stringing ? The hole is drilled so i'll install the stud but it's very unlikely i'll ever attach the bipod .

Don't have any solutions for ya but, I agree 100%. I bought one too and the stupid thing bounces all over the place. I took it off and now it just occupies space in my safe. :roll:
I had the same problem with bounce using a bipod. I solved the problem by using my padded scope cover beneath the bipod feet. This solved most of the problem of bipod bounce. Of course the weight of the rifle (about 12 pound sniper rifle) helps to control the bounce a bit too. HTH

Thats how it goes. bipods on a hard bench really bounce. Its less so on the soft ground. The Mil-issue M-14 bipod really jumps on a bench.
I remember in RVN training when the M14 with a bipod was used they, the SF instructors, threw a sand bag over the hand guard. Of course they were firing full auto.

Bipods on anything other than the ground bounces. It did it on my 700PSS, my AR in 6.8 and the M14 as well.

For bench rest, sandbags works the best for me.

I think the bounce is caused by the "rubber" feet that Harris uses. To test this, I put a couple of furniture "sliders" under each bipod feet and this allowed the rifle to recoil more normally, front to back. This setup also allowed me to keep on target and faster follow up shots.

I tried to make something more permanent but when disassembling the bipod, I found out that there is a small internal spring in each leg tensioned by the cross roll pin. Just getting it back to original form was a "pain in the butt".

I am sure Versa Pods and others with metal feet or metal sliders will not "bounce" as the Harris will, although I have not found a better bipod than a Harris.



This is a pic of an alternative bipod that I tried and it does not "bounce" which I attribute to the slider feet on the bipod.

A person who also recognized this occurrance and did something about it and made replacement "metal" feet is Bruce Piatt who markets his bipod feet through Brownells. He calls it the BI-SLIDE BIPOD FEET at http://www.brownells.com/aspx/NS/st...20864&title=BI-SLIDE+BIPOD+FEET&s=46173#46173 .

I think if you put anything under your bipod that can slide on your supporting surface, you will see that the bounce becomes less evident and should help with getting rid of vertical stringing.

Give it a try, I hope this helps. I tried all day to respond to this thread yesterday, but the weather here certainly affected by Internet connection.

Never heard of that or saw it before but i copied the pic and will take a bipod into one of the machinists at work . He loves working on anything related to guns so i try to keep him happy . :D atr
BIPOD BOUNCE is a very real phenomena.

When I was a police sniper I got away from using a bipod when lots of the other guys would use them. The problem comes from the inconsistencies of surface one finds oneself shooting from. most folks figure you will always be on a hard surface of some kind. I don't.

the harder the surface the worse the string.
a backpack will be a consistent "bench" to use no matter wht it is rested on.
This is a cheapass and lightweight solution, but here goes. Buy two hackysacks, make a small hole in them and remove about a third the sand inside. Stitch them back up and attach them under the feet of the bipod when shooting off a hard surface. Essentially carrying around your own "soft ground".
I went to a sniper pack and never looked back. I will use a Bi-Pod if I have to but if I have a choice I use a sniper pack always.
I have at least 100 rounds of boxed .308 on the bottom for weight with bags of cleaning patches on the top for cushion.

Here are two versions of the packs that are available.

You can use an Alice pack or a backpack filled with towels also works very well.

It takes a little while to get use to but I found I tightened up my groups a considerable bit using a pack type support.
I just keep making my M14 heavier. It is 29 pounds now with loaded mag. It doesn't bounce now!!! I shoot a lot of little varmints with it far off so it's more of a heavy barreled varmint rig now than anything. I still deer and hog hunt with it though and sometimes swap out the stock and go to a match.
