3G lightweight build?

Recommended Posts

What upper and lower would be best for lightweight and take the abuse of 3gun?

I was thinking of using the Magnesium Mag Tactical but am leery after reading some reviews.

Suggestions?

Stock, handguard, barrel, and optic mount very likely will drive the total weight of your build more strongly than the receiver set. Have you already selected those components and that is why you are down to shaving a couple of ounces off of a receiver set?

Have you ever wondered why none of the top shooters have a MAG, Carbon, Polymer lower for their match guns? While it might be fun to chase a few ounces, there is no real benefit with the receivers. Get a quality forged 7075 lower and upper and call it good.

I think Daniel Horner was using a Mag Tactical lower, not sure what upper though.

I think Daniel should show up shooting in red PJ's flip flops and shooting a Sten...then we all would be.

And don't forget to loan him your Automag.

OP, your choice for optics and mount will have a greater impact on weight that your upper/lower set.

For sure Daniel could shoot anything better than most of us but I would think he would not choose equipment that might fail on him. Does anyone know if he is still using Mag Tactical lowers?

Doesn't Mr. Horner use a MAG lower?

I agree lighter barrel, handguard and other areas will result in less felt and actual weight. But if you want to go light, by all means have fun and go light. Invest a couple months and a couple thousand good rounds of practice and let us know the benefits and limitations of what you built.

I built a lightweight rifle for having fun at our local 3 gun matches where we don't shoot out past 40 yards. It is super fun to shoot. I weighs in at 6 lbs with C more rail ride. I can shoot it faster at close range than my 18in 3 gun rifle. Build one and have fun with it. Everyone who shoots it loves it.

If you want to go lighter you could use a smaller brake and a upper that does not have a foward assist. The only regret I have with it is the brake I would rather the Afab as it felt the same as with the titan. JMHO

I agree, there are a lot of heavier things you can cut weight with besides the upper/lower. However me and my buddy just ordered a handful of Mag Tactical lowers, when I get my hands on them I'll relay my review. I will also add that the reason we decided to try these lowers out is because we got them dirt cheap.

The reason they are dirt cheap is because people tried them and found them not worth it. I still have one, but would not spend any money on one again. The "paint" does not stay on them, the pin holes are longer to account for the softer material and they don't hold the pins tight. So you have to end up using oversized pins and since the material is so soft, the holes wallow out pretty quick.

Mark or Pat , anyone,

Do you have any experience with the 2A light set of upper and lowers ?

When did you grab that story you linked because at 6:43pm EST on 26 December 2015 the rifle has a different listed configuration. It is as follows:

Notice that the compensator and rail are both different. I have to wonder how much involves sponsorship or other affililation arrangements between either Mr. or Mrs. Horner. Or perhaps it's more chasing performance? BTW, I've been on the same squad as Mrs. Horner and had many opportunities to interact with her socially at the match. I didn't know who she was. She was very nice and seemed approachable, well-grounded, etc. So, I don't mean for my comments to be misinterpreted as negative against either of them.

Proof barrels in their AR profiles and lengths suited for 3-gun are not significantly lighter than all steel versions. Once you get to 20"+ lengths for 308 and related calibers you begin to see more significant savings. For long bolt gun barrels it can be very impressive. Just ask Proof yourself, like I did.

In the end, I'm really only posting since the list you showed as coming from the article and the one I read a few minutes ago have those small differences. I found that odd and unexpected.

You need to look at the profile difference as well as the length. Compare it to a similarly profiled barrel and the weight savings start showing up. If you profiled a bolt gun as silly as a M4, weight wouldnt be that different either.

Yes, I was already taking that into account in my statements. It was meant to be an "apples to apples" comparison. We may have different definitions on what constitutes "significant"

weight savings. For me, it was really showing up at the 20" mark on the 6.5 Creedmoor barrel. .875" at the gas block but something like 2lb 10oz. Their chief engineer told me himself. Looking atht ebolt bareels you see the percentage weight savings begins to take off because of thicker profiles that are traditionally used.

On a 14.5" 223 barrel with a .750" gas block the returns will be diminishing in a hurry (length giving rise to increased moment of inertia more than the profile). They'll be there at least to a small degree, but for me the juice wouldn't be worth the squeeze. I'm absolutely *not* a Proof hater. I'm very intrigued by their products and have had a very favorable impression of their customer service with my inquiries. I happen to do research in carbon fiber composite applications to spacecraft, so I'm a Kool-Aid drinker on CFRP. If I had the money to risk, I'd build a 20" 6.5 Creedmoor AR with their barrel and give it a spin.

Anyway, I wasn't intending a threadjack. Apologies for the brief divergence from the OP topic.
