Then again I’m only 22 but I got goals
Are you seriously only 22? You’ve got plenty of time and you seem to be on the right track.

Hell, at 22 I was getting paid on Friday, blowing every cent on alcohol and fat ugly chicks (they looked good after all the alcohol) all weekend and then waking up Monday morning, hungover as hell and broke as a joke.

More from the AR armorers bench.........Today is trouble shooting a RO727 Colt M4 Carbine that has stoppages, erratic failure to feed or failure to eject after the gun gets hot, mostly failure to feed.

Gun history....the carbine is 10 years old, has about 18k rounds through it (all Federal M193 5.56). The rate of fire has been almost exclusively semi auto, with an estimated less than 5% of rounds (< 750-900 rounds) fired in full auto over the course of 10 years.

The rifle is inspected annually for defects, internally focusing on extractor/extractor spring, ejector/ejector spring, bolt lugs/cam pin hole, firing pin condition/protrusion.

The recoil spring and extractor, extractor spring/elastomeric bumper/"O" ring was replaced at 10K rounds, part of a PMCS service schedule (replaced whether they need it or not). The complete upper will be replaced at 20K.


Quick visual inspection......gas tube at the carrier key end is trash! The flange is completely worn smooth.

The carrier key was still secure and the gas tube/front sight base transition was fine, so no gas leaks there. Replaced the gas tube, checked tube/barrel nut alignment (good to go). Probably a good idea at this point to replace the gas key too, so went ahead and knocked that. Ground the staking down, removed the bolts ,replaced the key. If the key is staked properly you will break the Allen wrench or strip the bolt head if you don't grind the staking first.

New key (left) vs old key (right)......no erosion at the rear key gas port/bolt body interface, that's 100% normal, never seen it erode there.

New key (right) vs old key (left)...hard to see in the pic but there is visible erosion into the mouth of the old key. it's probably still serviceable, but might as well shit can it anyway.

Test fired this morning....210 rounds, first 3 mags on full auto as fast as I could dump the mags to get the it HOT. Then semi auto for the last 120 rounds firing about 1 round a second. Worked fine, no issues.



Two interesting things. First the rear bolt carrier key bolt hole was drilled a little too deep and actually perforated through to the bolt interior channel. It's a complete non issue because that's the bold tail section of the carrier, aft of the gas chamber. Here's a pic with a light aimed through the channel. You can see the hole clearly.

Second, the bolt carrier is actually a Colt Canada (Diemaco) production part. Where the "C" is usually stamped there is a "Stylized D". The rifle came straight from Colt/Harford to here and there is nothing else upper/lower receiver or parts wise that has any Diemaco markings. Anyway, I just thought t was interesting to find the Colt Canada part.
