So with the recent internment of winter, I decided to tinker with my Windham Sight Ready Carbine (SRC). The goal was a series of short DIY projects that provide significant improvement over factory parts, while being both inexpensive and completed without major tools. I opted to do this in several stages beginning with stock replacement (Part I), the pistol grip (Part II), and then hand guards (Part III). If you’d like to read my review of the Windham SRC rifle itself, you can view it here. Likewise, MagPul’s CTR Stock review can be viewed here.
Part I: Stock Conversion to a MagPul CTR Stock
Step 1: As always, assume every weapon is loaded when handling it for the first time, and remove the magazine and clear the weapon in a safe direction. If there are any questions consult your Owner’s Manual.
Step 2: Extend the stock to its maximum length.
Step 3: Push down and hold the Lock/Unlock lever.
Step 4: Pull up and hold the stock’s adjustment locking pin (this may require the use of pliers or vice grips to get a solid enough grip).
Step 5: Finish sliding off the stock from the rifle’s buffer tube.
Step 6: Ensure the new replacement stock is consistent with the buffer tube size for your appropriate rifle (i.e. for the Windham SRC it has a Commercial-Spec buffer tube as opposed to a Mil-Spec buffer tube). Place the replacement stock, in this case a MagPul CTR stock, over the buffer tube.
Step 7: Press down and hold the stock’s Lock/Unlock lever.
Step 8: Hold up the CTR’s locking pin while sliding the stock forward on the buffer tube.
Step 9: Release both the Lock/Unlock lever, and pin, while allowing the natural spring tension of the CTR to hold the stock in place. Test the stock’s alignment by sliding it forward and back to the minimum-maximum stages.
Step 10: That’s it! Enjoy the new stock…
