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 MOE mil-spec buttstock is Magpul’s flagship buttstock, with a unique A-frame design that has become the standard for the firearms industry. This stock has a mil-spec diameter, compatible with most buffer tubes for current production AR-15s, like the Ruger AR-556 and Smith & Wesson M&P 15.
  • 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 SPEAR Handguards. Further details on each component below.

AT3 SPEAR M-LOK Handguard

With 9″, 12”, or 15” lengths available, the SPEAR handguard is ideal for customizing your next AR-15 build. If you’re starting from a stock rifle, make sure you purchase a Low Profile Gas Block with the handguard.

Lightweight & Durable

  • Slim and lightweight M-LOK design, with attachment points at the 3, 6, & 9 o’clock positions and lightened Picatinny rail at the 12 o’clock position
  • Durable 6061 aircraft aluminum alloy construction – designed to take a beating
  • Picatinny top rail perfectly aligns with AR-15 flat-top upper receivers, both forged and our AT3 Billet Upper
  • Handguard uses screws to clamp around the barrel nut, with anti-rotation tabs and anti-slip screws that ensure a rock-solid lockup

Easy to Install

  • Installs clean and secure with only a few simple steps – all you’ll need is a torque wrench, vise block, and vise. Click here to view our instructions.
  • Seriously, it’s easy. Torque down the barrel nut, slip the handguard over, and tighten down the screws. No need for special plates or adhesives for a rock-solid fit
  • Perfect for assembling a new build or upgrading an existing rifle – it’s compatible with most upper receivers on the market
  • Once you’ve got it installed, you’ll have plenty of room for M-LOK accessories and adapters

Exceptional Fit and Finish

  • Durable matte-black anodized finish resists scratches and provides an attractive surface that matches the rest of your build
  • Vented top rail reduces weight and dissipates heat from shooting
  • Finger grooves down the length of the handguard provide a more ergonomic hold and a unique look

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. Additionally, this rail will not work with gas blocks that are irregularly shaped or exceed 1.3 inches in height or width.

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.

Jeffrey Hall
Great product, not all there though.

The grip looks great, it’ll fit perfectly.
The hand guard look amazing as well.
The buttstock, on the other hand, didn’t get put back together AND was missing all of the parts to complete it. Only came with the buttstock and the adjustment lever. The customer support was amazing, helped me all the way through, the biggest problem is to get it replaced was 4-6 weeks out so they sent me a black one. I’m getting that one painted to match, not what I wanted but now I’m not waiting. IMO they could’ve offered a discount for not shipping what I wanted and paid for. Especially the fact that the burnt bronze stock is $70 and the black one was only $40. Kinda chicken shit if you ask me. I’m in the service industry, I get things happen out of your control but you have the option to make it right. Won’t be purchasing from here again. Nor will I recommend.

I also see it says to reach out to them (bottom of the email), isn’t that what I did with customer support?

So sorry things did not work out well for you, Jeffrey. If you are unwilling to wait, we can give you the burnt bronze stock for the price of black.
