AT3 Tactical SPEAR XL with Forged Upper Combo - ODG SBR Build

The AT3™ SPEAR XL M-LOK Handguard is Suppressor Ready, Light Weight, and Easy to Install!

This suppressor-ready handguard free floats the barrel for accuracy, and maintains accuracy even with a suppressor underneath the handguard. Mount lights, grips, even laser modules where you need them with M-LOK attachment slots and a full length top rail. All without compromising your rail’s real estate while you’re running a silencer.

With 12” and 15” lengths available, the SPEAR XL handguard is ideal for customizing your next AR-15 build or upgrading an existing rifle with a buried suppressor. If you’re starting from a stock rifle, make sure you purchase a Low Profile Gas Block with the handguard.

Frequently Asked Questions

Will this fit my AR-15?

The SPEAR XL is designed for use with Forged Upper Receivers, our matching Billet Upper Receiver, and many other designs on the market. In most instances, it will also require the use of a low-profile gas block that fits underneath the rail. Piston systems may also be used, but check with the manufacturer first for exact dimensions.

This product will not work with non-milspec upper receivers like the Bushmaster Carbon due to the non-standard barrel threads.

We’re always glad to verify the fit for your rifle, just contact us! And if it doesn’t fit, we are glad to return it for you. And if you’re new to AR-15, we recommend watching a couple of the videos on our installation video page to understand how the process works.

Will this fit my Suppressor?

The SPEAR XL has a 1.74″ inside diameter, which will accommodate most suppressors for the AR-15. Typically, we recommend a 1.5″ diameter suppressor for use with this handguard, to ensure that the M-LOK slots are still able to be used surrounding the suppressor. Larger suppressors may have trouble fitting M-LOK accessories.

What tools and additional parts are required?

For parts – most setups will require a low-profile gas block.

For tools – we recommend:

  • A vise and non-marring vise block for holding the upper
  • A torque wrench to assure you stay in the AR-15 barrel nut torque range while timing the barrel nut (30-60 ft lbs)

NOTE: Due to the circular shape of the SPEAR XL handguard, the Magpul Gen 2 MBUS Iron Sights are not able to be activated. However, the Magpul Gen 3 MBUS and other iron sights will fit onto the SPEAR XL with no issue.

OCL Polonium fits under like a glove

This hand guard is fire. Put a 12” ODG on a 7.5” build with an Otter Creek Labs Polonium and the look is exactly what I was shooting for (pun intended). Thanks AT3 for making this hand guard. Amazing product and customer service.

Thank you for your glowing review! We're thrilled to hear that our AT3™ SPEAR XL handguard was the perfect fit for your build and that you were able to achieve your desired look. Our team at AT3 is always happy to provide top-notch products and customer service. Happy shooting!

Quality supressor ready handguard

I purchased rhe 12 inch version of the Spear XL for my 12.5 inch 300 Blackout barrel and for the price I wasn't expecting too much other than a decent M-Lok handguard. To my suprise the finish, fit and feel were exceptional and it feels great in my rather large hands. I was a bit disappointed when I couldn't use my MBUS gen2 front sight with this handguard but I won't knock the handguard for me not scrolling all the way down the page to find the disclaimer about that particular front sight. Now I just have to save up for and find a good deal on some BCM sights or go cheap in the meantime with some UTG Pro sights. Other than the need to time the barrel nut this was a no brainer installation and the lockup to the upper is tight with the anti-rotation tabs. When I need another handguard this is the one I'll be looking for on another build, maybe the 15 inch for a 16 inch barrel.

Thank you for your kind review of our AT3™ SPEAR XL Suppressor Ready AR-15 M-LOK Handguard! We are happy to hear that you are pleased with the quality and fit of the handguard. We apologize for any inconvenience with the front sight compatibility, but we appreciate your understanding. We hope you enjoy using the handguard and we look forward to serving you again in the future!

Excellent quality

Installed on my 300Blk dedicated suppressed its large and feels better on the hands when operating.
wish they had more size options for example 9.5”, 7” options maybe an idea?

Thank you for your feedback! We are so glad to hear that you are satisfied with the quality of our AT3™ SPEAR XL handguard. We will definitely take your suggestion into consideration and look into offering more size options in the future. Thank you for choosing AT3 Tactical!
