Zeroing Colt pencil barrel

[mark5pt56]

Skinny super models need love, too!

Yeah but the chunky ones appreciate it more.

What were your results?

Cheers, Steve

Steve,
I haven't had a chance to run the experiment yet. Maybe later this week.

Hearing all this talk about how finicky pencil barrels are (“ooh, after 10 consecutive rounds I need to rest and cool down, my POI is off now.”)

It makes me think of them like skinny super models throwing tantrums on a photo shoot. “It’s too cold out here!! I can’t work in these conditions!!”

And just like barrels, if they had some meat on their bones there wouldn’t be no problems. Not picking on pencil barrels, variety is the spice of life. Just cracking a joke at their expense. 😜

Yes, well like the skinny models the pencil barrels have pleasing slender lines and don't weigh that much....

Steve,

When I tested mine I used the same lower for each different upper. Told myself that if I used the same exact lower everywhere that I could rule out any differences caused by this one or that one having a nicer trigger or whatever.

I know it shouldn't but still...

Already said I do not own any pencil barrels but if I had to venture a guess your results (a SOCOM compared to a pencil) are going to be about the same as mine comparing an HBAR to a Gov Profile. After you heat them up a few mags worth you will notice a difference.

Wish you luck and hope you have fun with your experimenting sir.

They sure try harder. Lol

I will use the same lower [one of many great things about the AR15..], both will utilize iron sights, and both have a standard front sight tower.

Nothing at all wrong with iron sights friend.

Nothing at all wrong with iron sights friend.

My opinion too. When I first got into 2 gun matches I shot irons because I didn't know what kind of optic I wanted. I learned a lot using them and I like the clean light look of irons. A good optic is better of course so I ended up with an Aimpoint Comp M4 w/ Aimpoint 3x magnifier.

I always sight in with irons first.

Ballistic Advantage and Faxon barrel test. No noticeable zero shift after a mag dump with either.

[jsbhike]

Same test.

Faxon(not much if any shift due to heat) vs. Colt SP1(fair amount of zero shift due to heat).



Small/single samples and all that good stuff.

Curious what your newer(I assume) Colt barrel does when hot.
