It's good to see a manufacturer involved in education. Other companies would probably have just scrapped the entire lot for the few bucks they'd have received. These damaged or end of life parts are far more valuable as training tools. Good on SOLGW for offering these up to you!
I have a War Sport barrel with the gas port off center, still put a few hundred rounds through it before I replaced it. Didn't realize it until I had someone dimple it for the gas block.
I was going to make a joke, but the comments below remind me that education--especially concerning firearms--is serious business. There is certainly a lot of learning to be done with those parts!
It’s from the rapid temperature change when shooting, particularly for the spicy rifle rounds or for anything fully automatic greeting frequently mag dumped. It’s not an issue for most people under typical use, your firearms will have some fire cracking in the barrel but it’s only an issue if it starts affecting accuracy. If you look into a used barrel it will look like it’s got scales, that’s fire cracking.
I believe I've also heard SOTAR use the descriptive term "Alligator cracking." It's very easy to recognize with a bore scope - it looks scaly like an alligator's hide.
Question: Why is the Gov't profile so common, even now that bayonets aren't commonly in use and people aren't using flashhiders to bust open boxes? I notice that even KAC and LMT *seem* to use what resembles a slightly modified Gov't profile for their 5.56 rifles. Why not a continuously tapered profile?
Love solgw’s lifetime warranty. Really waiting for them to have other profile barrels and would probably exclusively run them. A sub moa Hanson or similar efficient profile would scratch the itch for good!
@@jimdavis303 Oh no, guess it's time to prep the bank account lol *unzips wallet* Sub moa, all the barrel sizes and a proprietary profile for good weight and heat dispersion? Count me in!
@@SchooloftheAmericanRifle So the reaction rod has a fit that's too loose for the splines to properly hold the locking lugs which causes all the stress to focus onto the index pin? Geez, I hope my bev block hasn't doing the same thing.
@@Freedomishere-im6ug I had 3 Barrels bought in 2022 . One 16 and 20 From Brownells and one 16 bought from Primary arms .All ''cold hammer forged'' All 3 started shedding chrome from all lands right off the throat and patches between the lands further up the barrel at a very low round count,under 500 rounds. Brownells took them back with store credit.Primary arms gave me store credit for the other one. The reason I am putting this out is I sent one of the 16" barrels back to FN and they told me '' this is normal wear''. I know I am not the only one having this problem. I own barrels from 4 other company,s . And yes they are all CHF and chrome lined.
@@SchooloftheAmericanRifle absolutely, I got a 223 wylde function and throat gauge on the way from ptg I have extension headspace gauges and regular ones I’ll be checking with and I’ll be sure to check the OD of barrel extension with a ball anvil mic, as well and the index pin and upper receiver index pin keyseat even though I’ll be truing the BCM thermo upper in lathe and bedding it with 680 I still prefer minimal allowance in case I want to swap with a mil-spec upper.
Nice to see company send their 'junk' into the right hands. Very valuable teaching and learning materials.

As they say "One man's trash is another man's treasure".
In the educational scene "Known Bad" parts are just as valuable as "Known Good" parts. There's a reason I love SOLGW and not just for their products.
As a former tech school teacher donations like this are fantastic to get.
How many Air Force years?
Showing barrel fire cracking and port erosion in different stages of barrel life would be interesting.
I bet there's a wealth of knowledge to be gained from these. Awesome of solgw to send this stuff
Love SOLGW
Probably not the biggest motivating factor but the advertising that this will undoubtly muster is absolutely priceless. Epic move SOLGW.
Aloha from Hawaii's 2A community 🤙🏾
Thank you Sir
Very cool! Spectacular learning tools! 🤘🇺🇸#ARJunkie #AmmoJunkie #2ARights #SOTAR #SOLGW
Pretty cool. Makes you want to tip a pint of Sam Adams at the Green Dragon Tavern. Maybe throw some tea into the harbour.
Very cool to get so many examples donated!! 😎
That's quite the donation.
Outstanding information, and better yet examples of what to look for.
I have a War Sport barrel with the gas port off center, still put a few hundred rounds through it before I replaced it. Didn't realize it until I had someone dimple it for the gas block.
Thanks for all your content Sir.
Wow they left some NOX muzzle devices in a few.
The fight to keep the 2nd Amendment alive through education, communication, and selflessness warms my heart
Now build a gun where 6 wrongs makes a right ;-)
Great company. God Bless Texas!!
SOLGW seems cool as Hell. 👌🏻
Please make the 8-Hour video going through each item. Pretty Please.
Yesssssss
Where's that Junk Gun barrel I sent you? the one that swallows both a throat gauge and a muzzle gauge, lol.

Cool.

I see the bad barrel i sent to you a while back!
That's the barrel of a gun, right
Good for SOLGW. not many manufacturers have the balls to publicize their scrap. Too afraid of image. Some would have sold this to shooters!😢
What's "fire cracking "?
That a great donation by SOLGW!

Give us a couple weeks…

Does SOLGW quality match that of BCM, Daniel, and LMT?
You guys ever get any out of tolerance bolts? If so, what was out of tolerance?
Yes. We have many. Bolt Face Depth, Bolt Face diameter, Bolt Lug length, Firing Pin Hole dimension, Firing Pin Hole run out, and Bolt Tail diameter.
How do you bend a steel index pin with an aluminum upper? 😮
Happens often. The Reaction Rod is usually the culprit.
@@SchooloftheAmericanRifle So the reaction rod has a fit that's too loose for the splines to properly hold the locking lugs which causes all the stress to focus onto the index pin? Geez, I hope my bev block hasn't doing the same thing.
Can I have that keymo QD FH? 😂
I got a FN CHF 16" that started shitting chrome at 480 rounds now has 1000 and looks bad.
@tonyc223
How did you figure that out, from cleaning?
You reach out to FN?
Chf =cold hammer forge
When have they chrome line one of those barrel
Al tho that some funny click bait

@@tonyc223 what was the part number if u know
Was that a criterion core ? Wonder what happened?
It's shot out.
@@SchooloftheAmericanRifle gotcha thanks Chad I’ll be checking mine out when it arrives apparently they’re great barrels can’t wait.
@@peeeoii2738 they are good barrels. My only suggestion is to check the basics like headspace and how well it fits the upper.
