| Hello and thank you for the information I have learned so far! I have a question about possibly upgrading my DPMS bolt carrier assembly to chrome or titanium. I was wandering which one would be better, and if it was even worth the extra money to do this? Will it help any in either accuracy or ejecting shells? Thank you. --Tim |
| I dunno'? I heard Titanium is better than Chrome "harder". Titanium is very light weight, hard stuff, I got a diver's watch I paid 300 buck's for and it is made of solid titanium, really light but it will not dent believe me. So I dunno what is best for an AR, a couple guy's here said it's really not better just more money and the bolt carrier has a pretty gold color to it. |

If it's a gold color, that is Titanium Nitride. A coating applied to steel to improve surface hardness.. most titanium alloys are silvery grey.. Chromimum plated bolt carriers are pretty well proven, having been used for a long time.. As to making a bolt carrier, and bolt from Titanium, unless the buffer had it's mass increased, or the buffer spring replaced to compensate for the reduced mass, I'd expect a lot of sheared rims, and failures to extract..

Spend your money elsewhere. At best, a chrome or TiN-plated carrier will be slighly easier to clean (a mil-spec carrier will be chromed in the expansion chamber [where the bolt goes]). At worst, it can cause excess wear in your upper reciever. It will not improve either accuracy or reliability. Note also that the military does not allow their old rifles, which used to have chromed carriers, to be deployed; they are only allowed for training use. The military hasn't purchased chromed carriers in almost 35 years, and they put more wear on their rifles than you probably will, and under harsher conditions. -Troy |
