Product Description

What’s in the Box

  • Windham Weaponry HBC Rifle
  • 30-round Magazine
  • Detachable Carry Handle
  • Rifle Sling
  • Hard Plastic Gun Case
  • Windham Weaponry’s Transferable Lifetime Warranty
  • Owner’s Operating and Safety Manual

A team of the finest firearms people in the U.S.A. has been re-assembled to bring to market the highest quality AR type rifle possible. These good Maine folks - all former employees of Bushmaster Firearms - offer many years of experience in the industry, and all look forward to working with you, to serving your needs, and to building you a great rifle. And Windham Weaponry will back up that promise of quality with a Transferable Lifetime Warranty on their rifles.

Windham Weaponry’s HBC model is their “heavy barreled carbine” and a close cousin to the MPC model except for its barrel. The Heavy Barrel profile features more thickness under the handguard area, and a straight machine turning from the sight base forward to the slight step before the muzzle threading. Some shooters feel the heavy profile provides more rigidity and accuracy, but either way its all 100% Windham Weaponry quality.

Accuracy, durability, fit, finish, value, this carbine has it all, and with Windham’s Lifetime Transferable Warranty, you know it will retain its value for years to come.

(5 out of 5) great rifle
by Terry from Otis Orchards, WA on March 23, 2016

8 days to ship. Must be pretty busy at the warehouse. Great products, good prices. I'll be back again.

(5 out of 5) Windham HBC
by David from Lewisville, Texas on November 21, 2016

Great weapon, about 300 rounds down range and no issues. Took about 9 rounds to zero. Very happy with the rifle.

(5 out of 5) WW HBC
by Scott from Knoxville, TN on January 21, 2017

I took the rifle to the range today to sight it in. I was very surprised. It was as the manual said; close - 1 click low and right was all it took. I put about 150 rounds through it - a fun gun to shoot. It feels good, and I can hear a difference between the bolt chambering a round, versus the old M&P15 I had. It's a good rifle. I'd put it up against one double the cost.

(5 out of 5) 1st AR15
by Tracy from Little Elm, Texas on May 20, 2017

I researched them for 5 years before I made the purchase. I really like this firearm. It was on paper out of the box at 100 yards. I would recommend this product to any one looking for a quality AR.

(5 out of 5) Windham HBC
by Scott from Knoxville, TN on June 29, 2017

This is my second AR purchase after the S&W AR in the last couple of years. After researching and watching online reviews, I wanted an AR which reminded me of the M4 carbine, built to last, and was ready to shoot out of the box. The HBC didn't disappoint - I used a 25m military target to sight it in. And, my first 3 rounds were incredibly close to dead center iron sights - one click of the back sight and I was hitting the black silhouette. Never had a rifle been so dang close out of the box. The recoil is negligible and keeping the rifle on target is quite easy. I don't think the HBC would let you down regardless of the environment.

(5 out of 5) Windham HBC - Excellence!
by Scott from Knoxville, TN on March 31, 2018

I'd bought the HBC after seeing some reviews of it - I liked the idea of the heavy barrel, iron sights, lifetime warranty, and the story behind Windham. I took to the range and used a military 25m qualification target to check sights...1 CCW click on the rear and I was hitting dead center I find that extraordinary because I wear full lens magnifier safety glasses when shooting...my vision is not the best anymore. Highly recommend this rifle.

(5 out of 5) First AR
by Don from Bedford, TX on December 26, 2018

I'm an AK guy and always have been although, I've shot many AR's. I knew one day I'd have to acquire an AR and I have been putting it off. When the guys on the files posted that the WW HBC was on sale, I couldn't pass it up. I received the rifle about a week after ordering, so not too bad this time of year.
The rifle is flawless inside and out and the best part is that it shoots like a dream. The extra 8 ounces on the barrel make the already soft AR recoil even less. The reviews are all true and the Windham story is heart warming.

(5 out of 5) Great rifle!
by Khayree from Fort Washington, MD on February 20, 2019

I purchased this rifle several years ago. It was my 1st AR. I originally paid much more for it. When Sportsman's Outdoor Superstore had the sale with free shipping, I had to get another! Great quality rifle and fast shipping. I will do business again with Sportsman's Outdoor Superstore.

(5 out of 5) Great Rifle, Great Customer Service
by Jeff C. from Philadelphia, PA on December 28, 2020

This is my second Windham rifle 5.56&.223 and 7.62x39 and I could not be happier. This particular rifle 5.56/.223 I had out to the range once and it performed flawlessly. I ran both 5.56 and .223 through the rifle with no issues. The irons were pretty spot on 100 yards out with zero adjustments. The heavy barrel makes a huge difference in the performance and compensation for recoil. The rifle was fairly easy to break down and clean. Sportsmans customer service is outstanding as always. This is my 5th purchase through them. Shipping during these times is tough, but they seem to be improving on getting their products out the door.

Great gun! I have been waiting for it to go on sale here. When it did, I had to have it!
