MicroBest Chrome BCG - Pictures and Comparison

This is only pictures and a comparison. There are tons of durability reviews if you do a search.

MicroBest is the OEM for many big name manufacturers. BCM, SOLGW, etc. They offer a bunch of configurations in a handful of finishes. This is the all chrome, C158 variant. It also comes in Phosphate and Nitride. The chrome option is available with different material extractors and gas keys as well as unique fasteners and Sprinco springs. These carriers run anywhere from $90 in phosphate up to $165+ in chrome with different options.

This is the base MicroBest chrome finish with C158 bolt BCG and I planned on installing Sprinco extractor spring and gas rings. When I took it apart I found a 5 coil CS spring and heavy gas rings. I believe they are Sprinco but the BCG was not listed as containing such and I can't prove they are Sprinco. I did not change them as a result. I paid $118 shipped to my door.

I have a Brownells chrome BCG that I purchased last year. I do not believe it is made by MicroBest. It was listed as having a 9310 bolt. The markings are lasered instead of engraved like MicroBest. The original extractor spring and rings were pretty soft so I changed them to Sprinco. I paid $90 for the Brownells BCG, they are now listed for $120. I would choose the MicroBest over the Brownells but there is nothing wrong with the Brownells and will continue using it. The Brownells BCG has maybe 150 rounds on it.

The last picture is a bolt face comparison of the Brownells BCG, MicroBest BCG, and a no-name BCG I bought for $40 five or six years ago. The no-name part is likely Chinese; it is out of spec in every way possible. You can see how bad it is with the naked eye looking at the lugs alone.

I believe the MicroBest branded BCGs to be the best value options on the market today. I have been using their phosphate BCG's for many years. The chrome options are the sweet spot for quality, finish, and value. Everything you need, nothing you don't. If you do a web search for "chrome microbest bcg" you get tons of options at very good prices. I hope this helps.

I can't insert pictures, only add them. The MicroBest is all chrome and new, the Brownells has phosphate fasteners and is used.

ARC -- "AIR"-Brace mount ... any experience with these ?

I am considering the the ARC Air Brace mount for an AR-10 rifle.

I have the M-Brace mount and it is awesome (and very heavy) -- But I have not seen or heard very much regarding the 4-ounce Air brace.

Anyone have any experience with the Air-Brace mount? ... Considering it is ARC, I expect the build quality is good. Any thoughts of strength/durability?

Older weatherby vanguard issue

I've been doing some work on an older Weatherby Vanguard in a .270 WSM. The issue it's having is that the bolt drags at the end of its throw when closing and again when opening. It's to the point where it has to be forced closed then forced back open. I've concluded that the lug and cam on the bolt act oversized when entering their slots in the action I tested this by coloring the parts with a sharpie then running the bolt. The drag marks on the parts seem to indicate that only the half toward the bolt handle is dragging. There's also dragging on the sides but I assume that's to be expected. Now I'm tasked with finding out what's out of spec, the cam and lugs? Or their slots in the action? What is a good way to conclude these things without a micrometer? I haven't checked headspace yet because I don't have a set of gauges for the caliber (because i wasnt sure it was applicable but probably yet another good reason to own a micrometer) but I have checked torque on the action screws. Any feedback would be helpful thanks in advance!

Springfield 1922 M1 & M2

I just bought this Springfield 1922 M2 and realized that magazines were tough to come by. And I have read that the M1 and M2 magazines
are NOT interchangeable. I took a chance and bought a M1 magazine to see If It was something that I could alter in the mag to make it work.
I found it to work flawlessly as purchased. My SN is 2259B and the B indicates that it has been through all of the arsenal modifications.
My magazine was a repro and from comparing to the photos from the seller, I was nearly certain that it would work prior to ordering it.
The are sold on eBay and Gun Broker thru Joes Pawn. So you may be able to get more mags for your M2 that work.
My next project is to manufacture a scope rail that doesn't drill into the receiver but uses the rear sight screws and the barrel diameter
as a place for some sort of saddle to rest. The saddle area will most likely have N50 magnets in it to hold it to the bbl. securely.
The rear screws should keeps it's location locked in place.
