Ok, I'm not prepared to do a full review, but I will make a few points.
First off, I LOVE this rifle, this is about my favorite rifle overall, and absolutely my favorite .22.
The Carbon fiber barrel is every bit as accurate as the steel barrel on my B14R.
I like the stock. I wish it had an adjustable comb, but the lack inspired me to mount my scope lower than I had originally, which helps minimize the need.
The magazines.
The actual Bergera mag is good for molding kydex mag pouches but thats it. It's like you showed a chinese company a picture of a 10/22 magazine and they made a knockoff.
I only use proven 10/22 mags, and I generally try to run at least 100 rounds through each mag before I "trust" them. I have found that out of every 10 factory ruger mags, one is absolute trash with loading/feeding issues, and at least one more is slightly oversized and will feed but not drop free on my target guns. Those mags get painted for use in my appleseed rifle which is old and sloppy as heck - every mag Drops free from that rifle.
So, I already had a fairly large pile of mags that were proven in my target 10/22s. Every magazine that I proved in a 10/22 has also worked flawlessly in the Bergera.
A further word on Magazines.
I have fully transitioned to the CLEAR 10/22 factory 10 round Ruger mags and I don't like the newer "frosted" nearly as much as the older non-frosted. My reject rate for those is almost double that of the old skool black and the smooth clears. I ordered 20 of the frosted clear from an online retailer about the same time I bought this rifle (because it was a smokin deal). Of that 20, two seem internally rough and don't feed smoothly, and FIVE feed OK but are varying degrees of oversized that cause them not to drop free in any of my target rifles. Since I now have over a dozen "rejects" I intend to make a project out of seeing what I can do to "fix" the problematic mags. I will also see if I can find a way to rehabilitate the ones that won't feed right.
A word on the Bergera and feeding. The BXR is noticeably tighter than even my Kidd, and seems to require a squirt of oil every 50 rounds or so to remain all slick and happy. .22 Schmutz is gooey which means it wants to be cleaned alot more often. This goes double for the magazines... This problem is exacerbated by only firing standard velocity rounds which typically have less oomph to operate the action. When I zeroed and tested this rifle I noticed that I could feel when it was getting sluggish, then a couple squirts or rem oil and I was back in business. My gun likes to be run WET.
