Let's talk about weight... putting your rifle on a diet...

The recent discussion on Free Float, got me into thinking about one of the reasons I bought my AR and what I finally ended up with.

My Sport in her final form, weighs in getting up close to 9 pnds (8.6 w/ mag). In my opinion, that's still light for a "battle rifle". Heck, next to what some of our troops had to carry, its downright hilarious. The ergonomics and everything why I set it up, was to be quick/accurate on target(s), at various/wide ranges (100 - 500+ yds)... and that she is (I invite anyone to come for a little 200 - 600 - 300 - 400 yd mag runs - quite fun on this setup). She's staying the way she is, more than likely.

I would like to start thinking about my next build, as it may not be too far around the corner... and would be geared more towards CQB (unless I decide to go with the .308 - then there will be some decisions to make).

On a new AR15 build, I would certainly entertain putting something like that Hogue on there, especially at that cost! It comes in at 8.5 oz. The Magpul setup I have (MOE handguard/MVG), plus the A2 is easily coming in over a pound... so I would see a significant/noticeable difference up front.

Anyone have any idea on the weight of the standard A2 sight, gas block? I can't do much about barrel length (here in CA), but I think I would see enough savings up there with just that, changing out the buttstock, going with a micro dot, would probably get me and keep me down around that 6 1/2 pnd mark, if not a bit lighter.

Even if I were to start with another Sport (I honestly think its an awesome base for a "sporting/range" rifle - and certain circumstances may require going that route)... I think you can see just from these comparison pics, out of the box and final build there would be a lot of changes made. Could you get much lighter than a Sport, throwing a carbine FF, removing the A2 and lighter buttstock?

EDIT: Another question. Being new to the AR platform. Would I see any advantage (I know it would add some to the weight)... going with a mid-length FF versus the carbine length? I see a lot of people, when they switch to FF, put mid-length or longer on their rifles...

I don't know what to say. The bone stock Sport comes in around 7lb.

My 308 rifles still manage to come in around 8.5lb-near 9lb.

This is empty, of course. So, you add a little more there.
I like them light, so I do not change much, especially up front.

When I hunt birds, it's a Mossberg 500. It's under 6lb. My go to 30-06 is right at 7lb.3oz. Considering how few shots one actually takes with it, I would not mind if it were 5lb. (I ain't recoil shy....)
I have rucked with some heavy rifles, and it's not too fun. The AR is a good hunting rifle, but I do not appreciate the weight much. For coyotes, it's all about long waits, and getting to high ground to glass from. While the Sport is ok for this, my 243 walks circles around it, so that's what I stick with. Coyote packs in groves are different, as is hog hunting; this will depend on where the hunting is. In a tree grove, you are walking a lot and shots are quick. For this, the AR platform is good. I keep it light, none the less.

I'd love to see an AR platform come in at 6lb flat. Boy, that would be nice. But the standard rifle is not a problem to hike with; I just don't add a lot of stuff I don't need up front.
 
I don't know the exact weight of the A2 front sight, but I'm guessing about 4 oz.. Take a look at the VLTOR CASV-M. It weighs in at about 14.3 oz. and will cover a low pro gas block. Removing the A2 sight and factory hand guard, adding a lo pro gas block and the CASV, you may come in about 3 oz lighter, with the advantage of a full length free floated rail. Pop a set of MBUS and a micro on there and you're set. The CASV also comes with a set of attachment rails that can be placed wherever you like.

Good Luck and good shooting. :D
 
Interesting input. Thanks guys.

Though, I very seriously doubt this rifle would see those upgrades. If I bought a second Sport for my wife (doubtful), I would give some thought to it.

But, I'm thinking towards a future build and leaning more and more towards starting from scratch.

A little under, but here you go! 2696 grams = 5.94 lbs

Now I'm tempted to tear off some hardware. Go with the basic, just to see what mine weighs in at? Haven't weighed it without the optic, honestly. Think I would, especially being a ADM QD mount. But, its just always going to be on there, unless it breaks. So, I consider it part of the weight.

Still be interested if I took off the VFG, optic, light... what it would come in at? Suppose I could guestimate to.
 
For your long distance rig, I would remove the light and the vertical grip. Vertical grip and tac lights are more for CQB type shooting, not long distance, IMO.
 
Considering taking off the grip. I'm pretty new to the AR platform, so it doesn't really feel natural to me. That's why I kept getting them shorter and shorter. Though, I've kind of taken a liking to the little Magpul, I've found two different grip profiles I like using it (though, one is like the AFG type hold/grip)

Its primary role in the house and my safe, is backup HD/CQB. That's why I had to have the QD for the optic and insist on a co-witness for non-magnified (if I'm running my Vortex Strikefire).

For HD, I grab my 870 first. If its something outside and perhaps beyond my comfort zone with the boomstick, I'm going to grab that M&P. The light is the upgraded Polytac, shooting 220 lumens. It paints me a pretty nice, far picture.

That's why I have the vertical grip and the light. I should probably just take the optic off, while its not at the range. As our immediate neighborhood, doesn't really have any shots, requiring 4x and any that did, I'd have the second to put the QD on. It holds a pretty good zero (I don't readjust it, when I put it back on. It still hits where I aim.)

I considered setting up my Mini-14 for all this, but the AR is the better modular platform and a Big Boys Lego, so it made more sense, being more versatile IMO. My Mini is set-up, CQB out to 200 - 300 yds. The AR can fill that role and then take it out well past 500 yds (depending on LOS) with that ACSS optic, no problem. And I wouldn't want to be inside that beam of light, at night.

I bought my M&P, to get into the AR world but I also wanted a firearm that gave me some redundancy and shared duties with a couple guns. While it sounds like and I describe it as a backup... I really do enjoy it and it probably gets more range time than any other.

Note: Went ahead and pulled it out of the safe, optic off... weighs in at 7.6 pnds with loaded 10 rnd and 7.2 pnds without. I suspect if I pulled the other stuff off, leaving the nice Magpul upgrades over the OEM stock pieces, I'm certainly going to come in under 7 pounds. Wow... glad I gave this some more thought.

When I bought my Sport a couple of months ago, all I did was pull the Magpull folding rear sight off and install a Daniel Defense fixed type rear sight. Then I changed the grip to a Magpul version that is set farther back and puts my finger in the trigger without going into the trigger guard too much. I haven't weighted it, but it's fairly light with a 20 rnd. loaded mag. I just wanted a good basic AR that works, and with my Sport set-up that way, that is what I got. I have others with stuff hanging all over them, and I would not want to have to tote them very far. With the Sport, I can do that.
