Edit **I’ve had a few people ask. Here is the link to my test target if anyone is wanting to use it. https://veracitysolutionsllc.com/resources/ **
Finally got a chance to get out and test a few different uppers for POI shift and get pictures.
These are NOT to bash any company but to make aware an issue that could be affecting your shots when changing positions or bipod locations. The point is to test and know if your shift is consistent and repeatable and then accounting for it if the style of shooting and targets you engage warrant it. I have used several methods depending on what I am using the rifle for to work through this. *I understand this isn't super scientific and the data is limited, feel free to test for yourself. More rigid receivers, semi-monolithic and monolithic receivers help mitigate this issue.
1. Zero normally from bipod, and add the shift to my data when in other positions that would have a shift. (Ex. .3 MIL shift, Normal data when using bipod, add .3 MIL to positional data)
2. Zero inbetween the shift as the targets may be tall enough it is in the noise. (Ex. .3 MIL shift, zero from bipod .15'ish high and bagged position is .15ish low)
These were shot from a bench modified prone as neutral as possible to do my best of not affecting results from inconsistent pressure. The bagged shots were taken from kneeling using the same bench.
Harris BRM-S 6-9 Bipod was placed at 12.5” from the front edge of the magazine well, then at 3.5” away, then fired kneeling from an Armageddon Gamechanger shmedium w/ heavy fill. This was done to keep things consistent across each upper.
Uppers:
Semi-monolithic:
Ridgeline Defense RD-15 LPR 16” Proof Research (KGM R30) (Thermal fit and bedded)

Standard Barrel nut design:
SOLGW Broadsword M76 18” Proof Research (OCL Hydrogen) (Thermal fit and bedded)
Hodge Defense Pinchlock 18” Krieger (OCL OCM-5) (Thermal fit and bedded)
Ammunition:

Distance:
106.2 Yards (Vortex Fury 5000AB)
Weather:
