The Reptilia RECC·E is a collapsible carbine stock for AR-15, M4 and SR-15 rifles, fitting a carbine-length receiver extension.
A constant cheek weld at every length setting — the comb does not drop away as you extend.
Most collapsible stocks give you one good cheek weld and several compromised ones, because the comb geometry changes as the stock moves along the tube. The RECC·E is built around a comb that keeps the same face position across the adjustment range, so the sight picture you set up at one length is the sight picture you get at the next.
The construction is mixed on purpose: an impact-modified glass-filled nylon polymer body over 7075 aluminum and nitrided alloy steel hardware, at 12.0 oz (340 g) with a length of pull from 10.8 to 14.2 in (274–361 mm). Ambidextrous QD sling sockets are built into both sides, and a rubber buttpad plants the stock in the shoulder pocket rather than sliding off a jacket.
Key Features
- Constant cheek weld: The comb holds its height across every length setting
- 10.8–14.2 in length of pull: Fits shooters in light clothing or heavy gear
- Ambidextrous QD sling sockets: Sling the rifle from either side without extra hardware
- Rubber buttpad: Grips the shoulder pocket and protects the stock
- Mixed polymer, aluminum and steel build: 12.0 oz (340 g) with metal where the loads are
Compatibility & Fitment
Fits AR-15, M4 and SR-15 rifles running a carbine-length receiver extension. It is not the same stock as the RECC·E for SR-25 / A5 / AR-10, which is built for an A5-length extension — the two are not interchangeable, so check which receiver extension your rifle has before ordering.

Frequently Asked Questions
Which receiver extension do I need?
A carbine-length receiver extension, which is what most AR-15 and M4 builds already run. If your rifle uses an A5-length extension, you need the RECC·E for SR-25 / A5 / AR-10 instead — the two stocks are not interchangeable and buying the wrong one means it will not fit.
What does "constant cheek weld" actually mean?
The comb keeps the same height relative to the bore across the adjustment range, so moving the stock in or out changes the length of pull without moving your eye up or down. In practice it means you can shorten the stock for heavy clothing without re-learning your head position.
Are the QD sling sockets on both sides?
Yes — ambidextrous QD sling attachment points are built into the stock, so you can run the sling from either side without buying additional hardware.
