This AR-15, 6.5 Grendel Type II Ultralight Model upper assembly is made from the highest quality materials... every part is Made in the USA!
And Price Includes Shipping
This upper is not just assembled in Texas, several of the parts are made right here in Texas.
So with the high-quality materials, meticulous workmanship & incredible pricing you can't go wrong.
We use Anderson Manufacturing flat top M4 Mil-Spec upper receivers, forged and then CNC Machined from 7075-T6 Aluminum, providing you with the hardest and most durable material of any upper receiver!
The 18” SS 6.5 Grendel Type II barrel is made from 416R Stainless Steel, Heat Treated to RC 28-32 Hardness, and Stress Relieved! The barrel is incredibly accurate and durable and includes an A2 flash hider.
This upper has a 1:8 twist rate, US Made mid length gas system with steel low-profile gas block (Not usually found on uppers in this price range), and has a 15in US Made Hand Guard.
The hand guard is a 15in Guntec Ultra Lightweight M-Lok, Free Float, made from Aircraft Aluminum, hard coat anodized to improve strength and designed for shooters that want an extra long, very light hand guard with the versatility of adding attachments anywhere along the length of the hand guard!
The gun builders at Texas Gun Builders have over 40 years combined experience, led by an ex-Army Armorer. Our uppers are torqued to military specs & quality checked continuously.
This is an ideal upper for Hog or Deer Hunting at longer ranges. The 6.5 Grendel shoots flat and has plenty of energy for those long-range shots.

If you came here looking for a great deal on an upper assembly, or parts related to the AR 15 or AR 10, Make Sure You Keep Reading
Hi my name is Madison, and I'm the developer of this website.
I was also the lead builder of the AR 15 and AR 10 rifles and pistols as well as the upper assemblies, for Texas Gun Builders for several years, and then for the company that took over and ran this website as TGB Online until August 2018.
I have over 40 years experience with the AR-15 and eventually also the AR-10. I became an Army Armorer in 1981 after basic training.
I’m giving you my background because a few months ago the guy running TGB Online started screwing me around, and being the website builder as well as the gun builder I decided to break away, LOWER THE PRICES, and run things myself with the help of my son.
Because the website for Texas Gun Builders had such a good reputation with Google I decided to leave it online but no purchases are possible here.
My son and I have started a new firearms community called First Texas Tactical. The resource and information part of the website are still being finished and should be online within the next 2 to 3 weeks.
In the meantime, whether you just found this website, or are a past customer you can find everything you're looking for at the sales portion of the new site.
And the prices will be considerably lower
We don't currently sell lower assemblies but we're working on starting a partnership with a local dealer to help anyone looking for a complete lower.
You can call us at 844.220.2267 if you have any questions.
The contact links on this site are being changed, or already have been, depending on when you're reading this.
We're glad you got here, and if you didn't buy anything that I built in the past make sure you check out our new site you'll love the prices.
And if you're a past customer and know my work, thanks for considering us going forward.
