The new Arisaka Stock Angle Adapter Lite offers a one piece design with lower weight and cost compared to the original Stock Angle Adapter. It is designed to upgrade Magpul CTR stocks for precision use with two important features:
1. Changes the recoil pad angle so it is perpendicular to the bore axis.
2. Changes the stock to use Magpul SL pads.
You MUST use a Magpul SL, Magpul SL Enhanced, or SL Limbsaver recoil pad in combination with this adapter.
The adapter is meant to aid alignment and recoil management on semi-auto gas guns like the LMT MWS and KAC SR25. The end result makes the CTR stock pad angle similar to that of a precision bolt gun stock. The OEM CTR pad does not work with this adapter; you must use the SL Limbsaver recoil pad or a Magpul SL recoil pad.
The Stock Angle Adapter Lite also functions with the Bag Rider CTR, which can be added above in the drop down menu for a slight discount. Bag Rider compatibility is limited by the stock shape, so other stocks which share the CTR recoil pad and work with the Stock Angle Adapter may not be able to use the Bag Rider CTR, such as the STR Carbine Stock. We are currently working on a universal bag rider option (Q4 2025).
Mike Olivella from Praecore Performance was the catalyst for the Stock Angle Adapter:
The Stock Angle Adapter is the first installment in a series of precision rifle focused, ergonomic upgrades. The geometry of most popular carbine stocks support a variety of shooting techniques and work well within those requirements. However, if we take a look at any modern, precision focused bolt gun chassis, you will note that all of them feature a 90 degree angle for the recoil pad. This isn’t by accident. This geometry promotes greater contact surface area for one of the critical alignment components of a shooter’s position behind the rifle.
The finishing touch that can’t be overlooked is how Arisaka made this accessory to not only work with a few common carbine stocks but also allowed it to accept a popular aftermarket recoil pad. For gas gun precision rifle shooters, this upgrade offers your rifle a lightweight, custom fit solution for your recoil pad with an extra bump up in surface area for your rear support.
Additional length of pull (measured at the middle of the pad): 0.70"
Weight: 2.5oz
The adapter is CNC machined from 6061-T651 aluminum and MIL-A-8625 Type III hard coat anodized. Compatible with the Magpul CTR, STR, ACS, ACS-L, and MOE carbine stocks. Will not fit Magpul MOE Fixed Stocks.
