Hey all,

I'm looking for a lightweight upper for my AR. I have a 20 inch stainless bull barrel currently. Looking for something that is a little more carry friendly, but is still accurate. Thoughts? Mike

Alexander arms claims their 18" lightweight upper 6.5 grendel is 4.3lbs. Are you looking at only 223/556?

Try a RRA 18" ATH upper. It's a lot lighter than my RRA 20" SS bull barrel and it will be a tack driver - mine is.
Sorry. Partial to RRA since they are a few miles away.

I bought this kit awhile ago. I'm pretty happy with it.

Just a thought, but if you're just looking for a plinker, you can buy the Ruger AR556 or S&W for less than what I paid for that kit.

Thanks for the replies. Looking to not go much over $600 for the upper. I think I can sell my 20" upper for 450ish and want to stay within $200 net for a lighter upper. I'll check out the rock river upper and see what they have on sale, and the PSA ones too.

I'll vouch for RRA as well but mine are not their lightweights so no experience with those.

If you want a lightweight upper get a lightweight barrel from any brand that fits your budget and use a magpul handguard instead of a rail. Those two items account for pretty much all of the actual and felt (swinging barrel) weight. Like a stabilizer, the farther away from the pivot point (your shoulder) the weight is the more you'll feel it.

I would personally recommend building one yourself if you have access to a torque wrench for the barrel nut. The rest of the upper can be assembled with a crescent wrench and something to drive the pins in (punch/channel locks). If you get a gas block that uses set screws or is clamped by socket head screws they usually provide the needed allen key. There's tons of how to videos online and it's a fun afternoon project!
