Recommendations for AR-15 collapsible stock

[MillCreek]

I have a Colt Sporter SP-1 that was manufactured in the early 1980's. It has the original stock on it. I have been pondering a collapsible stock. Does the Collective have a recommendation for an excellent quality collapsible stock that I can install? I am looking for something well-made, durable and sturdy. I have used some collapsible stocks that wiggled all over the place.

Your Sporter will have rifle length buffer tube if it is original so you will have to change the buffer tube, spring and buffer to carbine length specs. You may run into cycling issues, you may not. I would think you would want an H1 or H2 buffer as you're dealing with a rifle length gas system. Someone hopefully will chime in with what you will need in regards to buffer weight to get it to cycle well.

Personally, I wouldn't sell any of the original parts as I think those old sporters are perfect the way they are and are going to be harder and harder to come by, that way you can always go back to original. And with how cheap it is to assemble AR15's I would keep it the way it is and start piecing together a rifle how you want it. But that wasn't your original question so I'll leave my recommendations at that.

When I combined my 20" upper and carbine/collapsible stock lower, I got short stroking on weak steel cased ammo. I had to change to a weaker buffer spring to get complete cycling with the weaker ammo.

I believe there are multiple solutions to this problem and this is just one of them.

I built an M4 and used carbine length buffer spring and buffer, for my taste it had too much recoil. My thoughts were either an adjustable gas block, or a heavier buffer. I chose an H3 buffer from Brownell's - worked like a dream. Never had a problem.

I would keep your sporter as is and just build/buy a carbine rifle.

As
<*(((>< said, you will have to replace the buffer tube, spring, and buffer to add a carbine buttstock. At the very least you will need a castle nut wrench and a Vice or AR block to hold the lower. As far as what to put on, all depends on your tastes. A simple M4 style buttstock will run you about $50. Because of the longer barrel of the Sporter you may want some more weight in the buttstock so the rifle doesn't feel barrel heavy. Magpul ACS stock is the heaviest one I can think of at the moment.
