PSA Quality; Can a Fire Damaged AR15 be Salvaged?

School of the American Rifle has done a 5 part video series on trying to save a fire damaged PSA AR 15.

When I saw the title of video one, my machinist, metallurgist, and welding background kicked in and I immediately said no.

Well, I couldn’t have been more wrong, mainly attributable to the fact the gun didn’t get extremely hot.

What followed was an extremely informative video series that not only teaches, but attests to PSAs quality. Many PSA parts passed Chad’s rigorous QC checks that many manufacturers fail that charge double, triple, even five times PSA’s prices on ARs. Chad notes this fact during his pre assembly inspection.

Hope you enjoy :+1:t3:

I think we literally posted this within minutes of each other, mine is over in general.

I almost posted this yesterday - had just started watching it.

His stuff is ALWAYS informative, and I almost always learn something new, or get a Correction on something I’m doing wrong by watching him.

Steel is very hard to melt, but that won’t stop some fires, e.g. what happened to this fire-truck.

Wheat melts steel ? I’ve had honeysuckle melt aluminum. Maybe the chassis was aluminum.

I’m surprised the aluminum lower wasn’t melted. When aluminum metal is placed right into a normal wood based fire, the aluminum usually melts.

Yeah, I’ve been watching the series all week and really enjoyed it.

I was waiting for all the episodes before I posted.

Same.

But once Chad started taking it apart, specifically the buffer, and those rubbers weren’t melted, my initial opinions started to change.

I know firsthand what heat does to 6061 and 7075.

Very interesting series, thank you for posting.

i really enjoyed watching this… just wish the build video was free, as i wish the test fire video was available too.

If it’s still $20 I’m debating paying. PSA introduced me to the AR platform a little more than a year ago (1st purchase for my youngest son’s birthday). He wanted one and after substantial research, which I typically do, led me to PSA. I can’t find the link anymore but somebody did a torture test on 5 different manufacturers on YT iirc 20,000 rounds, PSA was the only one to survive. I think it was a steel cased ammo test of 5 different manufactures as well. Barrel slice and dimensional/metallurgical exam at the end. Tula got removed early. I’ll try to find the Y T video again, they didn’t even clean them right. Probably should have posted this on the high/quality/low quality thread. Sold me on the PSA AR platform.

ive not heard of or seen that video… i’d have to say that would have sold me too if i had not known of psa before. thats quite awesome.

I think I got a couple of them strung together in my head, happens. One I did find again so far was a steel vs brass 20k rounds, 10 ea. I’m still digging.

the one that springs to my mind is this one from AK Operators Union, 5k rounds + torture tests

Thank you sir! Pretty sure that’s the one I’ve been looking for for quite awhile now and I did somehow blend both of them together in my head. I think there may be one more out there with a compilation of several of his tests. I think I was skipping past these in particular as they were from AKOU. I wouldn’t have back then as the AK platform was what I owned and enjoyed exclusively at that point.

the steel is destroyed . . . the aluminum is warped . . . turn it into your insurance adjuster or just replace it . . .

I know for a fact that if they are lets say in a house fire and just in a closet when the fire department comes and puts out the fire those are the guns you get are 50/50 workable steel. Now if you have your guns in a safe and the fire hits. Then the fire department comes and puts it out, the vapor and steam from the guns being in ANY !!! type of safe then your guns are completely destroyed and every part is unusable. The insurance companies even have different payouts and levels for in safes or out because of the complete damage after a house fire in any safe even the best fire safes on the market!!! So if you care about saving some serious cash on safes and insurance , everyone STOP buying those Fire safes unless you want a little one in your normal safe for documents and other things.
