The Most Modular Bullpup AR Conversion Kit

Turn your AR-15 into a compact, high-performance bullpup rifle – without sacrificing the parts and features you already love.

The REAP Scy builds on decades of military and civilian use of the AR platform, giving you a reliable, flexible way to upgrade your rifle into a shooter-focused bullpup setup. It works with both standard (traditional buffered) and bufferless AR uppers, giving you tons of build options while keeping the controls, reliability, and parts compatibility of the AR-15/M4/M16 system.


Why Go Bullpup with the Scy?

  • Shorter Overall Length – Keep a long barrel for performance, but in a compact size

  • Improved Balance – Rear-weighted design reduces fatigue while aiming

  • Better Control – Manage your weapon one-handed while multitasking (handling gear, teammates, dogs, or opening doors)

  • Faster Transitions – Bullpup design supports quicker movement and aiming


Modular Design – Build It Your Way

Use Bufferless Uppers for Ultra-Compact Builds

When paired with the Sickle stock, you get:

  • 14.5″ length of pull

  • Example: A 16” barrel build is roughly the same size as an 11” traditional AR

Compatible Bufferless Uppers:

  • Brownells BRN-180 (all generations)

  • CMMG Dissent

  • Faxon ARAK-21

  • Foxtrot Mike FM-15

  • PSA Jakl

Or Use Traditional (Buffered) Uppers

Pair with shortened buffer systems like The Stave to maintain flexibility with:

  • More common parts

  • Broader caliber options

  • 15.7” length of pull with The Stave stock system


Smooth, Responsive Trigger Feel

Bullpup rifles often have bad triggers—not the Scy.
Our custom linear trigger linkage adds less than 1 lb of pull weight while preserving the crispness of your favorite AR trigger.

💡 Length of pull = distance from trigger to the back of the stock. Average AR-15 length of pull is around 13 inches.

    The Scy is exactly what the description said it it. It’s not some flexible piece of crap. I do wish they would make a all metal one though. The trigger is crisp but don’t buy a flat CMC type. It will not work. Also you may end up shaving some of the poly down for a upper to fit. Not a big deal. Oh and a Gen 3 PMAG won’t work either. It’s that numb on it that keeps it from sliding all the way in. For a one size fits all kit these minor issues are not that big of a deal. I recommend this product and hope for more versions of this (maybe metal) to come out in the future.

    The polymer on The Scy is excellent, similar in quality and feel to a Glock lower. I must have an updated version because I can use Gen 3 PMAGS. For my build, I used an Anderson Manufacturing AR-15 lower receiver, CMMG lower parts kit, CMMG Ambidextrous Magazine Catch, Geissele SSA-E Trigger, and a FM Mike 15 Gen 2 as an upper receiver. For a cheek rest, I used Magpul XTM Enhanced Rail Panels to cover over the picatinny. With the 16-inch barrel, my bullpup is slightly over 26-inches in length and at 6 1/2-pounds (unloaded), it is the lightest bullpup in my collection.

  3. Sandor Lin (verified owner)

    Excellent build quality and feel. Very well thought out and engineered. Really nice trigger design and feel. I have used this on a std AR aluminum lower as well as a polymer lower, both have run without any issues. Make sure it’s a lower w/o the trigger guard. Depending on your lower, there might be some small adjustments/modifications to make it fit and run perfect but pretty simple to do w/ a file/sandpaper/dremel. I would definitely recommend picatinny rail covers for your upper for your cheek weld, and definitely recommend an ambi mag release for an easier loads/reloads. The rear safety delete plug is a nice recent addition so that you only use the front safety. I have an ambi safety lever installed, but it may take a little trial and error fitting as not all ambi safeties will work depending on their shape. This is a must buy if you’re considering an easy bullpup conversion to build, perfect for the later generations of AR style uppers with the piston drive mechanisms (brn180, jakl, foxtrot, dissent). I prefer this conversion vs some of the other bullpups I have. Definitely recommend.
