View Full Version : U 15 buffer & spring ??

09-06-2010, 5:05 PM
Long story short. I happened to find a new unused u15 stock at a shoot last month. I am going to install a colt 20" hbar upper to it. The buffer tube on the u15 is shorter than an a2 stock. So do I just use a regular rifle length
buffer and spring ?

you can use a carbine spring and buffer for a 20 inch as well if thats the size of the buffer tube.

since I own a u-15 stock setup I know what parts to buy. Buy an ace ltd. CARBINE length extention tube. www.riflestocks.com there only 20 bucks and another 20 bucks for the carbine buffer and spring. total 40 bucks.
