| One more quick question, I was looking at two upgrades and want to know what they do and if they are worth it. The first is a chrome lined barrel for $20 and the other is a titanium bolt upgrade for $60. Not sure what the benefits of either of those two are, thanks for the help |
You don't "need" either. I wouldn't go with a titanium bolt, the standard bolts work just fine. A chrome lined bore will negatively impact your accuracy a tiny amount, but makes cleaning the bore a lot easier, as well as increasing the barrel life. |
Get the chrome lined barrel. It will extend barrel life, improve corrosion resistance, and help with the cleaning. Avoid the titanium bolt carriers. It's just bling, lots of cash for no real benefit. |
