Bipod Preload

Postby Marauder 1 » Mon Jan 13, 2014 4:53 pm

I was looking for the answer online and really couldn't get an "official" answer what is BiPod pre-load and how do you measure how much pre-load you need?

Thanks
Mark

Bipod preload is, slightly leaning into the rifle, loading the legs in a forward direction. This helps the rifle track rearward in a more direct line upon recoil. Most bipods fold forward so if the legs aren't preloaded, as soon as you fire the rifle the legs immediately start to fold which results in the barrel dropping. Preloading the bipod basically gives you a better followthrough on the shot. This is the way I understand it Mark. I do know my groups are much better when I preload. Especially at long range.

Well the marines tell you to load into the bipod. I doubt they are wrong.

Here is a video on the nitty gritty of it.
Oh and this guy is a marine
Watch on youtube.com


A while back 0933 posted the marine training video that they play for the troops and they load into the bipod.

Thanks for the info guys, I guess it's mostly by feel. I was thinking there must be a scientific formula for pre load somewhere. For example I suppose you could under load and over load if your not careful.

Also do you have to do the same with a bag? won't it move as well?

I don't think you need to load a bag. Never seen anyone do it

I've never heard of anyone loading a bag either. I would think a bag would travel straight back.

I've always heard to load the bipod with "light" pressure. You want to push foreward enough to move the legs to their rearward most position and put a tiny bit of pressure on them, but there is no need to be "flexing" or "bowing" the legs with pressure. I'm sure this will help you groups a little. It does mine.
