Bought some AR15 lower receivers, prior to the election last fall.
Used one up yesterday. My wife sometimes "mentions" that her AR15 is a little heavy. All I could ever tell was that it was lighter than mine.
Got the scale now. Now doubt what something weighs.
Anyway. I saw an ad from PSA and ordered one of the MOE carbine kits (came with a Magpul rear pop up sight). I put it together yesterday along with a sling from the parts bin and an Aimpoint I bought several years ago but didn't feel was making that particular rifle "better".
Anyway, the add said the kit weighed 4.3 lbs. I thought, Great, add the lower and the optic/sling and it should be pretty light, still.
Well, full assembled and on the scale it weighed 7 lbs. 10 oz. Her current carbine weighed in at 7 lbs. 5 oz. However, the current carbine has a thinner profile barrel so it balances differently in your hands, too. You may not be able to "feel" 5 oz. but you can feel the difference in balance. She'll be sticking with her current carbine and the new one will go in the safe.
Oh, picture of the PSA MOE carbine kit assembled on the lower. For $399 (the kit), $50 (the lower receiver, if I count the old Aimpoint from the used parts drawer ($287 - that's why I bought it, one of those contract over run deals several years ago) the combined price is pretty decent. I'll need to shoot it/sight it in to see how it groups.
