DSA US made metric FAL bolts

Have there been any reviews of the DS Arms US made FAL metric bolts? I did a search here but didn't get any results.

I bought one of their bolt carriers a month ago, the NTFE one. It runs like a top in my select fire FAL. Also ran one of their Para carries for a long time and it worked great too. That's all the help I can give.

I've had two come across my hands, from other blokes DSA guns, and one was cracked, the other broken. I'd post a pic, but Photo Phucket is holding my pics hostage. They can bloody well keep them.

I would use a worn out surplus bolt long before any DSA example.

Nothing more that I can add to that thread, other than the discraced (too corrupt even for Chicago PD) and Stolen Valor (fake commando) R1shooter still has not sent me the "new" bolt for evaluation as promised, nor has he disclosed how these alleged "new" bolts are marked to distinguish them from the known-defective ones that DSA knowingly and willingly sold - substituting them in parts kits so they could take the good IMBEL bolts out. It's The Chicago Way.

Our new bolts are sand cut like an L1A1 but with no other markings and the bolt accepts metric internals. The latest generation of our bolts are manufactured from 9310 alloy steel. The first USA made DSA bolts were 4140 and 45rc they were too hard and sometimes would break at the bottom corner of the extractor pocket it was kind of rare but did happen. We then we went with 9310 which is more expensive but super strong and used on the newest M2 barrel supports and heavy duty ar bolts. We have never ever shipped a single MIM or cast bolt as falsely stated by a few fal files members. We did 3 prototypes of a MIM bolt that we were considering for a 556 or 762x39 FAL but even in these calibers we were not happy with the results. As for this imbel bolt swap claim I have no idea what this is about and I could not find any information on this claim. We recently made a manufacturing video of our bolts.

Also just so members know we are not in Chicago and not even in Cook Co also most our vendors are not even located in Chicago and most our employees are not from the Chicago area.

What rocket scientist though that it would be kosher to build an FAL bolt out of 4140 to begin with?

Actually 4140 with a RC of 35-40 was fine we switched to 9310 because it's superior resistance to the normal wear and displacement of metal at the rear lugs of the fal bolt design compared to both steyr and our gen 1 4140 bolt also 9310 is also more flexible in heat treating. By using 9310 we have eliminated possible brittlness issues. 4140 can be used but 9310 is better.

The bolt in my Para has about 500 rounds on it with no problem.

DSARMS_REP: Do you know when the changeover in alloys occurred?

because you clearly marked the new version, so as not to confuse them with the defective ones you knowingly sold?

We didn't knowingly sell defective bolts when we discovered a very small amount could have an issue we stopped production and researched steels and heat treat specs and then switched to 9310. Very few 4140 bolts were even made and very few of those broke.

Yes, that's been "The Official Story (tm)" from DSA for some time. Yet all ten of the IMBEL kits I got through DSA arms back then had the IMBEL bolts removed and replaced with the defective DSA bolts. They didn't accidentally fall in there. Another (4?) kits sent here from other customers at the same time were switched also. So your "we didn't knowingly sell" is another bullshit lie! You knew they were bad, so switched them. That bullshit cost me around $1000. It's The Chicago Way. And you wonder why I have animosity toward DSA?

I really have never seen or heard of this and neither has anyone else here. Idk what to say about this one I will ask around again and see if someone did this and didn't report it but as of right now I confused on this one.

What about issues such as this?
This is a DSA barrel and gas block, which I found the gas piston hole drilled at a angle instead of in line with the barrel bore. When I asked DSA customer service about this, I was told that since I'd already breached the barrel to a receiver, it was no longer a warranty item. I had to source anouther gas block and replace the DSA block with a surplus one to make this barrel work.
Now mind you, I'm not picking on you, I'm trying to let you know that DSA problem parts are not limited to the receivers and bolts, there are other parts as well sold by DSA that fail at a alarming rate.

That is unacceptable customer service and is not in line with our warranty. Please pm me details on this.

Thanks

This was some time ago, details I can only convey by memory. I had the barrel timed, the whole rifle nearly built, and found the piston wouldn't align with the hole in the Imbel receiver. It's fixed now, I think I might still have the gas block in the reject pile, and will dig out the box if you really want it.
And, I see photofugkit has killed off every pic I had in my bucket. Arseholes.

Found the defective gas block, think DSA, whom you represent, will replace it with one that is in spec.? If so, I'd really appreciate it.

They knowingly sold them until they used them all up.
That is why people have not forgotten !!!
I changed out several for myself and others.
It was not a small batch.
They counted on many people having them for wall hangers / safe queens.
They where keeping oe bolts for contract guns.
The fact they continue to cover up is a major reason I still don't trust them.

I'm sorry that's just not true we destroyed around 300 bolts that were too hard we didn't knowingly ship any bad bolts. For that 2 year contract We used l1a1 new old stock surplus that we got from Pat Jones I am sure he has friends on here that can back that up. I don't think more than 40-60 overly hard bolts made it into guns and in a year were we sold around 2000 commerical guns that is a small amount. Also if anyone has a rifle that has broken it's us made DSA bolt we will replace free of charge of course.

I have a dsa made bolt I got a few(?) years ago but have never used it in a rifle,is there a way to tell if the bolt I have is of the correct material? I have to get it out to look at for any markings. Otherwise is there any way to send it in for checking before using? Also,were there any issues with other bolt parts like firing pins or extractors?

Thank you in advance for the reply.

I can confirm Pat telling me that he sold DSA a bunch of NOS Aussie bolts some years back

Not sticking up for DSA here, just an FYI

What batch of U.S. bolts went into the Imbel parts kits that you sold, and where did the Imbel bolts go? What would be the motivation for this swap?

If you were building rifles for a government contract, or for that matter just for sale to the general public, wouldn't you want a known good part to install in those rifles rather than one that you suspect to be defective?
