This furniture set contains 3 easy-to-install components – AT3 SPEAR Handguard, CTR mil-spec buttstock, and MOE pistol grip.
- The AT3 SPEAR Handguard free floats your barrel, improving accuracy, reducing weight, and providing plenty of room for M-LOK accessories.
- The CTR mil-spec buttstock is a higher-quality Magpul buttstock with a friction lock for stability, and QD sockets for slings. Designed for light, fast action, the streamlined A-frame profile avoids snagging and shields the release latch to prevent accidental activation.
- The MOE pistol grip provides legendary Magpul quality in an economical, drop-in upgrade for the standard AR15 pistol grip. The ergonomic, hand filling design combines aggressive texturing with storage core capability.
Use the dropdowns to customize your kit with 9 inch, 12 inch, or 15 inch SPEARHandguards.

Frequently Asked Questions:
Will this fit my AR-15?
The SPEAR is specially designed for use with our matching Billet Upper Receiver as well as the majority of mil-spec AR-15’s on the market. In most instances, it will also require the use of a low-profile gas block that fits underneath the rail.
This product will not work with non milspec upper receivers like the Bushmaster Carbon due to the non-standard barrel threads, and it is not compatible with most piston kits as they won’t fit under the handguard.
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.

Have Questions About this Product?
Great value for the price. Used to complete a build when I found myself with an extra upper and nothing to do on a couple Saturdays. Came out great.
I bought more than just this from AT3, waiting for my slick sided upper to arrive so I can mate it to the Spear Handguard, very pleased with the color match with the Magpul furniture. Excited for this build, AT3 products look and feel like quality and I can't wait to assemble everything and shoot it.
I just bought a butt load of parts from at3. Website is on point. Very well designed. Order fulfillment was exact. Parts are great. So far so good and I am a loyal customer for companies that do what they say they do. American made means a lot to me and i like My AR parts to have a USA stamped into them. Look at the pic, parts are perfect carpet camo Thank you! You just don’t see that attention to detail these days!!
Adding the FDE furniture completely changed the looks of my rifle. Changing was very easy to do and didn’t take very long. Does require some basic knowledge and proper tools but it’s worth it !
