To maintain the proper cheek weld, do you need to change the height of your cheek piece when you transition between the upright and prone positions or is there one position that works okay for both?
 
Re: Adjustable Cheek Piece?

^....agreed Top Predator but will I need to change the height setting of cheek piece to maintain consistent eye alignment when I transition between standing and prone so my POI does not change?

I am thinking about getting a stock with an adjustable cheek piece for better eye alignment and am curious how much adjusting they really need once the basic height is set.
 
Re: Adjustable Cheek Piece?

as i am cheap, i have a removable and adjustable cheekpiece setup that i can put from one rifle to another via the use of a pic rail attached to the side of the stock. i have graduation marks on it so i know where to adjust cheek piece to when i change it from one to another.

i do notice a little change in poi changing from bench to prone, so over the last year i "relearned" myself to more of a behind the rifle type shouldering (discussed on the hide numerous times) even off the bench to help alieviate the difference, with success, and not having to adjust anything. this is a path you may want to give a try.

another way is to mess around alittle and find that sweet spot to make a graduation mark to adjust the cheekpiece to when changing from one position to another for each position that your POI doesn't change.

or just dial the difference in, or constantly hold differently to compensate.

whatever way you choose to go, i'm a bigger fan of not changing anything on the rifle once it's "in" or zeroed. sort of using a constant anchor point using archery equipment. but if you are changing anything to a different position, i'd use the position that you shoot most as the baseline, then any adjustments to be made from there.


there really shouldn't be that much of a change at all if you so make an adjustment to the cheek piece, when i was adjusting the cheekpiece it was a matter of less than 1/4" in height. i actually found myself needing more of a forward or backward adjustment, along with a change in pitch to accomodate comfort, but that was way too much changing around, so the behind the rifle type of shouldering practice paid off in the long run for comfort, eye alignment, and no shift in POI. with some muscle memory, it also transferred over to offhand, kneeling, and sitting positions.
 
Re: Adjustable Cheek Piece?

The comb is always brought to the head. As the position gets higher the stock is higher in the shoulder to assure proper eye/sight alignment. In the standing position the butt of the stock will be mostly over the shoulder unless the shooter has an adjustable butt plate which can be lowered. The standing position may also benefit from a stock with adjustable pull where the pull length can be decreased.

In the prone position a longer pull may make the position more comfortable. For a low gun position the comb is brought to the head and the butt plate is raised if possible. The butt plate may also be canted to keep the rifle square. All of these adjustments when possible help the shooter maintain muscular relaxation. Interestingly, the M16 with A2 butt stock is for me more comfortable than any of my custom stocked match rifles which have a multitude of possible adjustments.

I test my loads from the bench and shoot everything else prone. I don't notice a change in POI between the two. If parralex is adjusted right you should be able to move some without changing POI. I do notice my natural prone position gets me a little closer to the scope so when I mount a new scope I get behind it in both positions and don't lock it down until I've found the happy medium. This is just me. I think the width of cheek bones and length of neck make this different for each shooter.
 
Re: Adjustable Cheek Piece?

Yes, the comb height has to be adjusted to meet your face when you change from standing to sitting to kneeling to prone.

If that were not so, target rifles meant to be shot from different positions would not have adjustable combs.

Your zeroes may change from position to position. That's what logbooks are for.
 
Re: Adjustable Cheek Piece?

Thanks for the comments on the question...I'm going to go the adjustable route and see how it works for me. Pretty sure it will help with maintaining a relaxed position as I am having to hold my head in position due to a lower fixed comb.

I always mount my scopes as low as possible to help the situation but being able to maintain cheek weld will likely help me track the shot through recoil better.
