Product Overview

16” Precision Barrel/Low recoil/Superb 9mm Ballistics

The Wasp model AR9 platform rifle, chambered in 9mm, offered by Rooftop Arms is a top-of-the-line build that is designed to be a precision pistol caliber carbine (PCC). This AR9 platform rifle is perfect for longer-range shooting where higher accuracy and stability are required. The minimalist buttstock and long but slim handguard pair perfectly to give it a stable feel. The 16” stainless barrel adds some weight and improves stability.  Of course, this premium barrel is paired with a short-stroke bolt carrier group and captured butter from JP enterprises for the ultimate shooting experience. The Trijicon Ascent 1-4 power scope is perfect for both close-range plinking or stretching out to 100-200yds to use the full ballistic capabilities of the 9mm Luger cartridge with the 16” barrel. Whether you shoot speed steel competition, or just want a great all-purpose PCC build, the Wasp model is an excellent choice.

Rifle ships with a premium carrying case, bore boss cleaner, 4 33rd OEM Glock magazines, 4 17rd OEM Glock magazines.

      Customer Reviews

      Dear Rooftop Arms: I can’t thank you enough for the pleasant experience utilizing your company. Most people are very hesitant to purchase an item costing vast amounts of money, especially when it is an out-of-state online purchase. Not to mention, requiring two separate tax stamps! You’ve been on top of everything when it comes to NFA items and your communication has been there every step of the way. The build of the firearm I purchased is beautiful as well as quality. I’ll be sure to keep you on my list of trusted firearm dealers. Thank you for being forthright and knowledgeable when it comes to purchasing ATF regulated items. You’ve made the process seem easy which is what people like to see more than anything! I’m sure we will do business again in the future. God bless.

      I am not usually one to do reviews however with something of this nature and wishing to share my experience, I felt it prudent to share. I have spent an immense amount of time researching how to build, what parts to purchase, and every other thing imaginable to build a matching set of AR-10 and AR-15. I wish I would have saved hours and found Rooftop Arms first! Let’s hit the high points: Made in America, Veteran owned, GREAT customer service. They had the ability to build the exact rifles I wanted with high-quality parts, and a difficult paint job that came out perfectly! Every step of this build far exceeded what I was hoping to get at the end. Spending a large amount of money, over $15,000, I wanted these rifles to be utterly amazing and they sure are! The highlight was Erin giving me a call and telling me my build was ready to be picked up. A few hundred rounds through both rifles and I am very happy! The last add-on will be to get my tax stamp through so I can add on my suppressor. They are walking me through that process as well. Thanks, Rooftop Arms!

      Working with Rooftop Arms was a seamless process. I bought their Ruby model AR15 rifle. Not only is the rifle absolutely stunning, but they made the California compliant process a breeze. I ended up with a beautiful gun that is always the talk of the range when I show up. I’m a very small frame lady, and the Ruby model is flawless and shoots better than any other AR15 I have ever shot! Don’t hesitate to call Rooftop Arms for all of your high-end firearm needs, you won’t be disappointed!
