Cross armory's website has 2 different models: CRSM308D for DPMS CRSM308A for Aero Precision Which one is this item?

Will this fit a Daniel Defense DD5V1? Expert Answer

We recommend contacting Daniel Defense to confirm your takedown pin size, most .308 rifles use pins that are around 0.280" diameter, however there are some models that use the smaller AR-15 pin size of 0.25". The DD5V4 may be one of those models. If it does have the 0.280" pins, this will work. It will not work if it has the smaller AR-15 pins.

installation by sal, Verified Owner, February 21, 2026
not to bad to put. took a while to get the old pin out. of course put the wrong sides in the wrong place so had to disassemble again. Make sure you put the correct sides in otherwise the lock is flimsy and would probably pop open during firing!!

Cross Armory quick takedown pin by Vic, Verified Owner, June 12, 2024
Clear instructions Required a little bit more time than I expected due to having to install a shim, but NBD. Will take some practice to get used to a little more bulk to get around for the safety selector.

Cross Armory quick rear takedown pin by Vic, Verified Owner, June 5, 2024
Not a quick install, needs some fiddling to get the proper clearance but it comes with the shims you’ll need. Mine used the .15 shim. Yours might be different. Follow the instructions.
