Look up "filthy 14" a DI 5.56 carbine with over 44,000 rounds through it without cleaning. Well lubricated, but not cleaned.

The real use for a forward assist on any AR is if you should make the mistake of "riding" the charging handle when chambering a round, then you can fully close the bolt.

Printing a barrel would be extremely hard, but making one the usual way is not.

3D printers get a bit more advanced and the whole idea of gun control becomes obsolete.

Another barrel to consider is Fulton Armory, they use Criterion barrels, which are made by another division of the company that makes Krieger barrels, in the other half of the same building. They are button rifled instead of cut rifled. http://www.fulton-armory.com/barrelfatitan185nmmedss1x10936gasblock.aspx

Depending on how important accuracy is to you, then you may want to reconsider the chrome lined barrel. The problem with chrome is that it tends to deposit unevenly inside the barrel.

Another idea I saw on another forum is to drill and tap from above down to the adjustment screw hole and put in a set screw to hold it, without locktite, makes it easier to adjust. Maybe drill holes in the free float tube to access the screws ?

So, is it an AR-10 or is it an LR-308 ? These are two different rifles.

Watching Magpul's Art of the Precision Rifle, Todd Hodnett is saying that 16", or 18" or 20" makes no real difference, all will work to 1,000 yards. Makes me reconsider a longer barrel, maybe I will just get a lighter one instead.

It has changed, the first time I saw it there were page numbers, now there are not... 5353_.pdf

Years ago I worked for a company that bought like that, they made big money processing it for reloading. Yes the lifespan of the brass may be lower, but it is less expensive and if you lose it in the weeds easier to replace. Is that selling price for scrap or reloadable ?
