    Interesting. Thanks for the info. Glad I asked

    Match grade roughly translated can mean "Buyer beware" and is the most over-used term in shooting sports today. Remember 10 years ago when everything coming to market was "Tactical"? Same effect. Match grade should imply a high degree of accuracy and is normally dependent on using "Match grade", or high quality ammunition. The term most commonly applies to triggers, barrels and ammo.

    I've never seen a match grade BCG before. That said, I'd never of match gas blocks either until I saw Rainier's and understood how their gas blocks are a better fit to their match barrels. If I wagered, Rainier had their BCG machines to higher tolerances for a precise fit in their upper receiver. Likely their bolts are headspaced to their match barrels too.

    Looking at the review of that one in particular and I'd keep away from it. Not sure the story there.

    Young Manufacturing was the first I remember using a carrier with that profile, but there are a lot of companies using it now. Young makes a great BCG, here's their details:

    National Match Bolt Carrier by Young Manufacturing, Inc. This bolt carrier is 1/2 oz heavier and has more surface area at the carrier front. These additions provide improved alignment of the bolt carrier as it moves in the receiver, tighter tolerances, more consistent bolt-lockup, and generally much smoother operation. This bolt carrier causes less wear, improved accuracy, and overall better function. All Y/M carriers are made using these high standards. The extra precision, quality, and post production processes are among the reasons top custom companies choose Young Manufacturing, Inc bolt carriers. You should too! (Available in AR-15 and M-16)

    Features:

    1⁄2 oz heavier than standard carrier

    Full diameter at carrier front provides increased support and alignment strength in battery position

    Carriers precision ground between centers after heat treatment

    Removes distortions from heat treat process Ensures straightness and accuracy

    Full hammer ramp machined for smoother operation

    Yup, Young was pretty much first on scene. Retailers were staking gas keys because Young didn't believe in them.
