DaddyNick 406 Posted January 21, 2021 Picked up an AR carbine build a few years back. Safe queen as I played with other carbines I have. I wanna put a full size A2 stock on it. As I understand I will need a full size rifle buffer tube so the A2 stock will fit. Anything else I need to do? Any mods to the upper so it cycles correctly? Thanks for any information.

Thanks for any information. Nick You’ll need an A2 spacer, and a rifle length action spring (correct name for a “buffer spring”) for sure. You may need a rifle buffer as well. Some guns will run great with a carbine buffer on a carbine or midlength gas system and a rifle length receiver extension (The correct name for a “buffer tube”), some won’t. What barrel length do you have on your upper? What gas system? Carbine? Midlength? Quote Share this post Link to post Share on other sites
DaddyNick 406 Posted January 21, 2021 Thanks. It's a 14.5" barrel with a comp to make it legal. As for gas system I'm assuming carbine with the short barrel and magpul fixed carbine stock. I like ARs but when it comes to the internals I'm a noob. Lol. Thanks for the info. Quote Share this post Link to post Share on other sites
High Exposure 5,635 Posted January 21, 2021 Measure how far your gas block is from the receiver. ~ 7” carbine ~ 9” midlength A lot of 14.5” guns (pinned brakes to make 16”) nowadays are midlength gas systems. Quote Share this post Link to post Share on other sites

Thanks man. Will measure tomorrow morning. It's buried in the safe. Quote Share this post Link to post Share on other sites
