Lightweight 20 inch barrel, free floated AR upper?

[zukiphile]

I think I know what I want, but do not find it sold in an already assembled upper.

I believe I would like an A3 upper with a lightweight or pencil profile 20 inch nitrocarburized barrel like the kind offered by DEZ in the link below.

While I would prefer a free float tube of some sort, I could probably get along just fine with a conventional front sight base and handguards. The idea would be something light, reasonably accurate and easy to clean.

Does someone already sell this, or do I need to find an AR armorer to assemble the parts?* Is any of this a terrible idea?

Thanks in advance.

*"Learn how to assemble the upper yourself and just do it" probably would not be the responsible alternative given my lack of patience and mechanical ability.

Call and tell him what you want. Although I think his are all stainless.

Not necessarily. Though most people who want a lightweight rifle use a 16" barrel. Is there a specific reason you wanted a 20" barrel?

Is there a specific reason you wanted a 20" barrel?

Specific may be too strong a word. I generally prefer 20 inch barrels based on the following observations:

1. The loud part is four inches farther away;
2. there may be a small gain in velocity;
3. the leverage of the barrel is greater for dampening wobble, given the same weight;
4. the whole rifle configuration is what I am used to.
5. this is a recreational item and I don't anticipate the extra length having any downside.


If there are reasons that this isn't a good configuration (which can be a valid reason for it not being offered), I am open to being educated about them.

The Remington R15 varmint AR has a thin 18 inch fluted barrel and a free floated handguard,

I think if I was going to pay for a Remington branded AR, I'd have to do the R-25 in 7mm-08. That would be pretty much all you needed in North America for hunting unless you're after brown bear or grizzlies.

Best,
