PSA Premium BCG price too good to be true? ($59.99)

Toolcraft is not a known quality brand?

Could be, but then why are there so many posts chiming in with doubts? Never heard anyone express doubts about a BCM part except maybe cosmetics.

Good:

Extractor looks fine and made properly, although I wish they would have listed a material spec for it

My take on it - make sure to inspect thoroughly and be sure you're happy with it. Buy it for the spare and inspect it. If anything, it's a good deal for the bolt itself. If you have a couple - I wouldn't go crazy and buying dozens of them. If you already have a few PSA spares I would look into Centurion, BCM, Colt, and other premium brands.

I agree with your last. As far as the first sentence I quoted, most folks list the extractor as tool steel. From what Ive found, the mil-spec for extractors is 4140 with 4340 as an authorized substitute. 4340 appears to be better:

4130
This low alloy steel contains high amounts of chromium and is often referred to as chromoly. 4130 steel has good machinability, ductility, weldability and strength characteristics. It is used for many different industries including the automotive, aerospace and machining industries.

4340
This nickel-chromium-molybdenum alloy steel is a very high strength steel. It is sought after for its toughness and for being used as a steel that will be highly stressed.

It is used in a variety of industries for different applications including the automotive, aerospace, and tooling industries.

The Relative Machinability Rating percentage based on SAE1212 as 100% is the following for cold drawn 4130 and cold drawn 4340 steel

4130 - 70%
4340 - 50%

Machinability Ratings:Note that a material with a machinability rating less than 100% would be more difficult to machine than B-1112 and material with a value more than 100% would be easier.

I'm ass-u-me-ing it is more than likely that unless otherwise specified the tool steel is 4140, since 4340 is higher quality.

BCM and PSA both list the extractor material as 'tool stee.l' So does Sionics.

I'm no expert, but just reading the posts in this thread there is enough doubt that I'd go with a known quality brand.

Why would somebody buy a PSA over a BCM?

1) Read the materials list - same materials

2) Today PSA Premium going out at $59.99; today BCM going out the door at $169.99. Hmmm, lets do that math.....as they say, take the savings and buy more ammo.

I believe PSA owns toolcraft

Tool craft is a premier bolt manufacturing company and they supply the Armed Forces of the United States. In the past members have posted pics of bagged tooltech bolts in possession of our troops.

My understanding is TC manufactures only the carrier and out-sources (assorted vendors) the remainder to their specs or to their customers' specs.

Based on?

To those that had issues, are you sure you purchased PSA’s premium BCG? They sell two different quality BCG’s, their premium and the cheaper freedom BCG.

Toolcraft is a manufacturer. They do make great BCG’s.
Now is the PSA BCG made by Toolcraft? Maybe but I don’t know.
But the issue is Toolcraft makes the BCG to the ordering company’s specs. So they can manufacture top notch quality parts for the military or other companies but if another company orders the cheapest parts made by Toolcraft then it’s lesser quality.

Remember, you get what you pay for.
