Normally I hang out in the Retro Forum but I'm in the process of building a little more modern rifle and I have a question that I'm sure someone can answer here. I am using a flat top upper with a 16" barrel with a mid length gas system. I'm planning on using an A2 rifle stock and I need to know what buffer I should be using. I'm guessing I should be using the rifle buffer but, I thought I'd ask just to be sure.

Yep. Standard A1/A2 buffer and spring.

^that. You don't want to run a carbine buffer in an A2 receiver extension. It should run fine with a rifle buffer, as long as your barrel's port is large enough.

While I am no expert by any means, I chose to run a Spikes T2 buffer and a full auto profile bcg in my 16" PSA mid. It shoots nicely and cycles perfect.

Definitely feels "softer" than the same setup in a carbine system.

I would start with an A2 buffer.

You need the longer rifle buffer if your going to use a rifle length buffer tube.

We use carbine buffers all the time at the shop.  The spring will stretch out to compensate.

A carbine buffer in a rifle length tube will allow the carrier key to collide with the tube and the rear of the lower receiver, since the buffer won't bottom out first. I hope you're misunderstanding what you're suggesting, and not actually using carbine buffers in A1/A2 tubes.

I use to run by midlenght with an A1 stock and a rifle buffer.  That was one smooth shooting combination.  David.

We do it ALL....THE........................TTTTIIIIIIIIMMMMMMMEEEEEEE.







LOL, relax, we do it for tuning reasons.  There's a homemade 9mm adaptor in the tube also.  Probably should have mentioned that in the other post,

Thanks for all the replies. I wasn't sure if the mid length gas system would make a difference as to what buffer I needed. It looks like as long as the buffer and the buffer tube are matched I should be good. Thanks again guys.

I have a Bravo 16" mid upper on a full A2 lower that I use for 3 gun that runs like a champ.
