Boise, ID – -(AmmoLand.com)- The AR15 is an incredible rifle but it largely overshadows the AR10 and its ability to shoot large calibers while retaining all the benefits of the AR15 platform. Interchangeable components and the flexibility to completely customize and accessories on the picatinny rail all come with a stock AR10.

2A Armament XLR-20 AR10

2A Armament is answering the call for large caliber, distance shooting with the superior XLR-20 design in the popular 6.5 Creedmoor caliber. The 6.5 Creedmoor has taken root among distance shooters and hunters for its accuracy qualities at short and long distances. It’s an incredible round and 2A’s experienced shooting staff does it justice with a rock solid, finely machined AR10 rifle.

The 2A Armament XLR-20 AR10 rifle has the option for KUIU Camo print for tactical and hunting uses. It also has a black stock option that suits most shooters as well. Like all of 2A’s rifles, the XLR-20 is machined to perfection using a CNC machining process. The Full Mass bolt and carrier is cryogenically treated and creates a comfortable shooting platform ready for repetitive shooting.

The biggest advantages delivered by the XLR-20 are the precision build, durability and consistent performance with every round that passes through the chamber. When it comes to a larger rifle, many hunters and shooters are prepared to take on the extra weight. The XLR-20 is so finely tuned that it only weighs 6.85 pounds, making it lighter than most small caliber rifles. If you are trekking across long distance and hauling your rifle through the backcountry for days on end, the weight savings are an absolute game changer.

Price and weight!


Many of the sentences could not be parsed for meaning! Read what you write!


Seemed perfectly clear to me, but English is not my second language.


Given that 30 caliber rifles are generally considered and accepted to be Medium Caliber Rifles, how does anything of Smaller Caliber come to be a Large Caliber Rifle?
