Cool!
I just completed more testing yesterday by taking a sample out of the inagural batch that went to Shooter's Discount and testing it in order to experience exactly what a new barrel owner will experience.
The very first thing that will be noticed, is that the first shot from a cold barrel, and the first hand loaded shot will land much closer to the next shots on a target. That is one of the benefits of good barrel tensioning of the German made Lothar Walther blanks.
We weighed them at 24 ounces. The actual barrel portion is 16.25", then the threaded adapter and weighted end cap extended the overall length out to about 17.3". Really stinkin' liteweight, but with the weighted nose they balance really well and provide what I call "Pointability", a perfect combination of balance and nose weight for steadiness offhand as well as off of a rested position.
The 416 Stainless shanks are heat treated on the breech end just as the factory barrel is done, and the fit to the receiver is snug as a bug. The laser engraving is also a very nice touch. The extractor groove is done in such a way (specific angle) as to promote a really good grab onto the rim, and the cut itself is right up to the radiused chamber lip. I've used nothing but factory extractors in my testing and had 100% reliable cycling.
The extractor leads into a very nicely installed chamber that is much tighter than a Bentz chamber, a design we've been toying with for several years now. Exceptionally high accuracy but with enhanced reliable cycling of a lot of the less expensive cartridges.
That leads down to one of the tighest 22lr bores found anywhere, with a final twist of 16.4:1. If you take a peek down the bore, you'll see nothing but a perfectly honed and lapped mirror finish underneath of that protective oil film. That meets a chamferred crown before exiting through the compact stainless threaded adapter and out through the stainless end cap.
The aircraft aluminum outer sleeve is a very nice satin velvet black done with a virtually indestructible epoxy powdercoat.
That is kinda the five cent tour.
It certainly isn't the least expensive barrel, but we think it has all of the right qualities that one should expect from an exceptionally high quality offering.
Each barrel is serial numbered, and corresponds to a particular batch run and then Dealer order, and every batch run gets random sampling to ensure performance standards meet expectations.
Here's the Carbine stocked testing rifle used on barrel number 0017 on Monday afternoon:
At this time, SHOOTER"S DISCOUNT is the ONLY place to get one of these barrels. They felt confident that these barrels would be just the ticket and did not hesitate to grab the inagural production run of the new Quantum series rifle barrels.
They should work really well in a suppressed application, with a true match grade chamber that supports subsonic ammo, "Jethro's Bunny Popper" has never been more able.
