| I have a Ruger AR-15 clone and I am thinking about putting an A2 stock on it. My question is what type of buffer would i need to insure proper function? The reason I want to go this way is because I don't feel the need for an adjustable stock since i fire from a rest with a bi-pod and prefer a fixed stock for that application. Thanks. |

What he said.
You can either run a rifle length spring & buffer which is about 5 oz. or save a few bucks and buy a spacer and re-use your carbine buffer & spring. I picked up a delrin spacer from Brownells for the A2 stock I have on a 9mm AR since I wanted to keep my dedicated length 9mm buffer. Make sure you get a carbine to rifle buffer spacer and not a 9mm spacer. If your current buffer is 1.5 oz. I'd recommend bumping up to the rifle buffer, it's noticeably smoother. I've heard running the carbine buffer with a rifle spring also works fine, and a rifle spring will probably cost you as much as the spacer. |
| to add to what the above posters have said... if you use a carbine buffer without any spacer in a rifle length tube, it will allow the bolt carrier to go further into the tube and the carrier key can strike the lower... if you want to fool with adjusting a rifle buffer, each steel weight is 1/2 oz... if you remove two weights (and replace them with 1/2" aluminum of the same length) you get a 4.2oz buffer which is close to the H2 carbine buffer weight... an A1 stock will shorten the length of pull... which is what I use on my 3 gun carbine... |

You might want to look at the Magpul FCS carbine stock. It comes in mil-spec and commercial and tightens down super solid on the carbine buffer tube. Gives you about a 12 inch length of pull. I believe a Magpul extended butt pad will give another 1/2 inch if desired.
As far a buffers go, most carbines with 16 inch barrels and carbine gas can really use a H or H2 buffers for better reliability. I run H2's in all my middys! That Spikes Tactical spacer really is a slick idea for the guy who wants to go with the rifle stock and tube to replace the carbine set up. |
