In building or upgrading an AR platform rifle, the bolt is, in many ways, the heart of the rifle. A quality bolt is part of what will make a rifle reliable, so it makes sense that the bolt and its carrier are one of those parts that precision manufacturing has really helped make into a part that can last for high round counts. If you’re looking to upgrade the bolt in your AR, consider the Rubber City Armory Titanium 5.56/.223 Bolt Carrier Assembly .
These, by Rubber City Armory, are seriously nice bolts. Made from titanium, these are sure to last basically as long as you care to keep it in the rifle. Additionally, the manufacturer has treated them with a proprietary surface treatment to make sure that they’re going to last for a very, very long time. The bolt face itself is of similarly high quality so that you can make use of it with high pressure ammunition. Given that this bolt carrier group is standard AR15 style, it’s a great drop in mod.  Adding to the modularity is the gas key, which you can adjust.This would be a fantastic fit for several kinds of users, but in particular it would make sense for a competition gun in which you’d expect a very high round count, or for precision shooters. Thanks to being in standard AR 15 dimensions, you can also drop in any other internals, such as the bolt or a firing pin, as you see fit, though the ones that come with this are excellent. The Rubber City Armory Titanium 5.56/.223 Bolt Carrier Assembly with Adjustable Gas Key is a great choice if you want to build one of the best AR 15 platform rifles out there.

Rubber City Armory: Being shooters ourselves we saw the need for a better surface treatment than what was currently being offered on AR-15 and other firearm parts. This translated into making bolt carrier groups of our own choice, with our premium surface treatment, setting us apart from the rest.
This has led us to further innovate into lightweight designs, making use of the latest technology, and surface treatments available.
