Title: AR buffers and stock question.
Post by: blackwolfe on February 19, 2010, 06:38:34 PM
I have been told that you shouldn't put a carbine buffer, carbine receiver extention (buffer tube), and carbine telescoping stock on an AR rifle, meaning a 20 inch or longer barreled AR.  When I asked why, the only reason given, was that it won't work.  Has any one tried this?  If it doesn't work, why?  Does the AR not function in this configuration?  Is it dangerous or damaging to the AR ?  I know there are differant weight buffers avaiable, which buffer should be used for a carbine telestock on a rifle assuming it can be done without problems?  Thank you for the input.

From my problem with buffers I figure it is because the rifle has a longer barrel and gas tube it builds up more pressure than the carbine so it needs a longer, heavier buffer in a longer tube.
A carbine stock is not long enough for a rifle buffer to function and a carbine buffer would not stand up to the beating it would take from the bolt at rifle pressure .

I doubt if it matters.

I've got a 1000 rounds thru mine without any problems. it doesn't seem to beat up anything excessively

It does matter, the short buffer tube needs the short, heavier buffer, and matching spring, both shorter overall as a matched pair. Side note,  I do like the inodine now Brownells hydraulic buffer, it is gentler and quieter than the standard buffer, really takes the twang out of the action.

M25,
So can you use the collapsable carbine stock, buffer, and tube on a rifle?  20 inch barrel?

The barrel does not matter, it is just the buffer tube, only so much room for the buffer and spring to compress.
