Mechanical offset is something every rifle owner should know about, especially if you’re using an AR-15 or other modern semi-auto carbine. Mechanical offset (or “height over bore”) is the reason your rifle seems to shoot low at short distances. Today we’re looking at why that matters and how to compensate for it.
The rifle featured in the video is a 5.56x45mm BCM AR-15 with a 14.5″ barrel and a pinned and welded FSC comp, a BCM M-Lok handguard, BattleLink Minimalist stock, VTAC sling, and a Steiner 1-4×24 P4Xi scope.

Don't I know it brother. I put a round through the chrome strip that ran right down the center of the hood on a Pontiac that way. Embarrassing
I shot the jaw off a white tail with a .45-70 because mechanical offset. Huge buck came out at 10 yards, rifle was zeroed for 100.
The vortex uh-1 has a second point that can be used at 10-15 yards or at 200 yards.
Great lead in for sales pitch
Old school film photographers know this as “parallax error”.
I practice a six o'clock hold for up close applications you know bottom of donut on the Eotech works great for me
I use a 3×9 by 40 zeroed at 100 yards and 45 degree off set iron sites for under zeroed to 25 yards just to correct for this issue. It makes transitioning distances much easier.
I was just wondering about this the other day. I'm blind and coming up with a system to read color through my scope so I can aim at a light/dark part of the target for aiming. but since I can't ajust the retacle, my system will always be a little above the bore. I thought one job of the retacle was to ajust your point of aim to make up for the scope being above the bore access
Another great video. I love your format and presentation.
Holy height over bore Batman!
This is why you're supposed to use the bottom edge of your Eotech ring for CQB.
Great subject. Always very informative. Always very well done.
I feel it's especially noticeable when using A2 iron sites
Love Ur videos😀 So informative and up-to-date 👍🏻
Just remember your hold-off for CQB and use a 100 yard zero..
Make more videos. Weekly. Daily.
You, Paul Harrell, and tnoutdoors9 are my absolute favorites. You're not trying to make yourself look good. You're trying to make us better.
I would definitely buy ammo from luckygunner.com. I just need to get a gun first!
Another great video for those who don't know.
Or, it's colder than when you zeroed it.
Is it possible to zero an AR to shoot both supersonic and subsonic 300blk?
Yo Sootch LoL
Is the standard for being zeroed lower for backup irons? Tried to zero my AR 300blk pistol with irons at 50, and no matter what I tried I couldn't get groups closer together than about 7in (longest distance between 2 shots). I still don't know if it's zeroed.
5:56 this is literally the entire reason I zero at 50. I’m too lazy for holding over
I would be fine with a 2 in drop on a 50 yd rifle. Middle head will blow the teeth out, lower head drops to neck, and torso is still going to hit something the person wouldn't want to have hit.
If you are only using your rifle for HD and not going to shoot more than 10 yards, why would you put a scope on it anyway?
Sootch: I’m probably gonna put a round through my hood because of the offset
Sootch: puts rounds through hood because of the offset
Sootch: surprise pikachu face
Thanks for the useful information.
My main home defense shotgun, a short dual pistol grip pump action, does not have sites. Problem solved.
At 3 yards i usually just use kentucky windage
Why YOUR AR 15 shoots low. 🙄
