Bore Sighting Irony

Biggfoot44 · Nov 5, 2015

Finly centered the windege on scope mounts, & bore sighting the 2.5x fixed power on the "MSR" Upper. Doe moves into the visuel point where I'm boresighting.

Double Sucuess !

#1 - Plmetto St upper w/ scope , windge is spot on.

#2 - Colt Commdo upper w/ 1:12 twist puts Fed "Bird" 62gr Pb-core fmj point first. ( Vs 62gr M855-ish which is full sidewys 10yds. Which points to possibility of 62gr bonded for deer , for both uppers.)

Ya lost me.... :confused:

While boresighting , deer w@lks in front of gun.

Boresighting w@s sucuessful , fixing multi l@yer p@in in butt th( h@d been frustr@iting me.

Different type of 62gr 5.56 works inste@d of tumbling from 1:12 bbl .

First two post w@s @ble to select words w/o using dre@ded "@" for (first letter) sunstitution , but it seems to h@ve been @t expense of undferst@nd@bility.

His "A" on his keyboard doesn't work.

He's l3t3. His Kung Fu is better than yours.

I'm still trying to figure out "bore-sighting" on a doe. Or was I supposed to insert an A somewhere?

That's a $5 fix at MicroCenter.

I've got stacks of keyboards at home, but doesn't help on the phone which is my primary 'net surfing device.

I was already boresighting on purpose. The doe then walked inbetween the scope and the aiming point. Tried to arrange a raincheck for her to return in about 3.5 weeks, have to see how that works out.

Many 62 grain bullets will not be stable when using a 1:12 twist barrel. Here's a place to start: https://www.ar15.com/archive/topic.html?b=3&f=16&t=545381

That's a start. Try not being so cryptic and we won't have to take 10 posts to figure it out. Just some friendly advice.

I was only able to today, because my home computer magically stopped letting me connect to MDS and other gun rights sites on 11/01 , and only magically began working again this morning. ( Would still let me access several firearm specifc sites, but not those with heavy 2A activism emphasis. )

Wait, wait. Colt Commando uppers are 1:7 twist.

Biggfoot44 · Nov 6, 2015

No, the modern ones do. Old ones 1:12 . From before there were 1:7 or 1:9 .

Biggfoot44 · Nov 6, 2015

Now that I'm back home to real keyboard.

This is not a civillian psuedo-Commando . It started it's life as part of a FA. Of course, at the time I set out to research to try to determine its pedegree. But turns out that it's not possable from just an upper.

Commando was a semi-offical nickname for several different Colt Model numbers , and never was an official US Mil weapon having offical configuration. It seems Colt did not make Commando for stock , but rather mfg each batch as they recieved orders. The concencus among Colt collectors is : 1. large orders could to a degree specify features 2. Colt would use components on hand at the moment, and they could be mixed in combinations they did not occur in the larger M16 or AR-15 world, and could be anacronistic for the era in which they were assembled/ sold. As well as I can WAG , points to M733 , from late '60s to mid '70s.

BradMac82 has seen this upper when he helped me build my pistol lower.
Skinny 11.5in , marked as chrome lined 1:12 , A1 flashhider. A1 upper reciever, teardrop foreward assist, no shell deflector. The person from whom purchased used it on his personal full auto, didn't think to ask at time if were the orig lower, or a different registered selective lower.

What you're describing is an XM177E2 upper, not an M16A2 Commando or M4 Commando. Colt never applied that name to the 1:12 uppers. (Sorry if I seem picky - I also happen to have a genuine M4 Commando upper from an FA gun.)
