Don’t worry, we’ll be doing articles on the Best AR-10 Uppers and Best AR-10 Lowers for all you builders out there who want something a little more custom. They’re known in the industry as one of the biggest quality manufacturers of lowers and uppers for other AR makers.

They also offer a wide variety of build kits, including various Create options that are available as limited runs. We’re price concise and like solid quality, and Aero delivers on that.

As you can see, the top recommendations were the ones tested, and Eric shot between 1.5 and 2 MOA, which is perfectly respectable for a <$2k .308 rifles with factory ammo. Aero M5E1, Tornado Match GroupsWith hand loads, Eric and I both believe the gun is capable of around 1 MOA to Sub-MOA accuracy.

While Eric used a complete Aero AR-10 upper, I went a more custom route for my 6.5 Creed moor AR-10. This is one of the things we really like about the Aero Builder’s Kits, they allow for a lot of flexibility.

Be it in .308 or 6.5 Creed moor, Aero built or custom parts, the M5E1 is a solid platform. Aero M5E1 (top) with DAMS LR-308 (bottom) Okay, first, it’s pronounced “Reaper” which is either cool, or a little too “edgy teenager with dark eyeliner” depending on your perspective.

For the military’s CLASS (Compact Semi-Automatic Sniper System) competition. The main difference between that version and the MAIN is the gas system.

Using Federal Gold Medal Match 175gr Matt put five rounds into a one-inch circle at 200 yards. Lori also makes a great line of AR-15s that deliver the same level of performance and reliability as their AR-10.

Daniel Defense makes good stuff, that shouldn’t be news to you. They hold a number of military contracts, and with good reason.

Brown ells has got you covered with their BRN-10 in .308 that revives Eugene Stoner’s battle rifle used in 1955-1960. While it is missing some of the improvements that modern style AR-10s have, it more than makes up for that in pure cool factor.

For a rifle that should be almost 6 decades old, it shoots perfectly and launches you into an old age of firearms, before everything was black and plastic. PSA AR-10 Gen 3 Adjustable Gas Block vs Gen 2It doesn’t magically make recoil zero…but it helps dampen the .308 cartridges when you configure it for your specific load.

And for uppers… I’m a fan of going stainless 18 to wring out some extra accuracy and velocity of the bigger rounds. Make sure you get a combo WITH bolt carrier group (BCG) and charging handle (CH) included.

The short version is that the 716i Tread is SIG’s more average person friendly AR-10. Right out of the box the groups are outstanding, the recoil is soft, and the system as a whole is clearly well tuned.

It’s a sometimes-finicky rifle that, when done well, can be one of the greatest joys to shoot, and one of the most versatile options in your gun safe. These guns are the best of the best in their particular niches and are perfect if you find yourself needing to hit something very far away with a very large bullet.

In this guide we'll be covering the best AR-15 hand guards, including free float and drop in options. They manufacture their own receivers and hand guards in house, which has led to them churning out parts in bulks.

In our own experiences along with everything we've seen across the internet, their quality control is excellent, as is their customer support in the unlikely event you have any problems. All Aero Precision's free float hand guards are made out of 6061 (T6) aluminum, which is generally the standard material across the industry.

They have both MILK and Named variations for all of their hand guard designs, but we generally recommend Milk as we explain here. It has a Pica tinny rail across the top with Milk style slots on the bottom and sides.

LengthWeight7”5.22 oz9”6.03 oz12”8 oz15”9.07 note that the mounting hardware will add additional weight and is the same 4.72 oz no matter what length hand guard you choose. This allows you to still mount your front sight to a flat and extremely secure surface while removing potentially unnecessary weight.

LengthWeight7”4.86 oz9”5.47 oz12”7 oz15”7.95 for the average AR-15 builder, one of Aero Precision's offerings should more than fit your needs. Here's a picture of an AR-15 I recently built with the Atlas S-One (with GUNFIGHTER FEE Rail Panels).

They have a stellar reputation and make reliable products that you can be sure will stand up to anything you throw at them. I've purchased a number of complete BCM uppers and have nothing but good things to say about them.

That's worth noting because I feel both are quality products made of the same 6061 (T6) aluminum. As you get into the longer BCM Cars, however, the price does get more competitive with Aero Precision.

One major advantage of the MMR vs the Aero Precision options covered above is that it has mounting slots at more angles. We've talked about Saxon in the past as being known for making super lightweight parts, like their pencil-thin and gunner-profiled AR-15 barrels.

Saxon Streamline Carbon Hand guards Saxon's Streamline hand guards are made from carbon fiber, which the company claims to be 40% lighter than aluminum while simultaneously being 10 times stronger. Although I can't speak to the specifics of those numbers, I can say that it definitely feels a lot lighter, yet still very rugged.

It's worth noting that Saxon's mounting hardware and barrel nut are also lighter than most, so you're seeing bigger savings in total. V Seven Weapon Systems has emerged as a high-end manufacturer of lightweight AR-15 parts in recent years, and they offer the lightest hand guards on our list.

V Seven Hyper-Light MILK Hand guard AR-15 V Seven introduces yet another lightweight material to our list: a blended aluminum and magnesium alloy. They claim it's 30% lighter than the typical 6061 aluminum while also being stronger, and the results speak for themselves (see table below).

With these features combined, it's arguably a better lightweight option for tactical and practical applications. LengthWeight7”2.8 oz9.2”3.5 oz11.1”4.3 oz13.5”5.2 oz15”5.7 oz16.5”6.2 oz For those of you with a fixed front sight base and delta ring assembly who just aren't ready to make the switch to a low-profile gas block, here are the best drop in AR-15 hand guards.

When it comes to the quintessential drop in polymer hand guards, most people's minds go to Magnum. The company literally created the MILK mounting system, which has become the standard today.

The two pieces fit around your front sight base, giving you additional mounting space. The downside to this longer aluminum set up is that it's heavy, weighing 14.1 oz.

Until recently, you could argue cost was a factor, as free floated AR-15s are generally more expensive. With that said, modern back-up sights have come a long way, as has battery life and reliability for red dots.

Simply griping your drop in hand guard, resting it on a surface, or attaching accessories to it can therefore affect accuracy. As the name suggests, they're free of contact from your barrel and “float” from your upper receiver to the end of the hand guard.

Absorb more heat when made from the same materials and offer worse ventilation. This also prevents you from potentially touching a hot barrel or even worse, shooting yourself in the hand.

Despite the added weight, I'm generally running up to a 14" hand guard whenever possible... and I have short stubby arms. Generally, it's now preferred to have just a Pica tinny rail on top, then Milk or Named elsewhere to lighten your hand guard.
