i have a dpms lower and i bought a magpul ctr stock and there is quite alot of play,i know there is mil-spec and commercial buffer tubes and im pretty sure i have a commercial one because of the slant at the end.im confused because i bought a commercial ctr and there is alot of wobble. so what is wrong?
 
Re: Im confused! Need help

well that's a good question because i bought it at a gun show and i know how sketchy gun shows can be, but airsoft ones are called pst ctr i think and this one is a normal magpul ctr. im so confused of why there is so much play, i dont get it.
 
Re: Im confused! Need help

Had the same problem with my RRA not being milspec. So changed out the buffer tube ($38) and problem solved. Now when I put the Vltor or CTR stock on there is no play at all.
 
Re: Im confused! Need help

its not a airsoft one, and i thought that a commercial tube and a commercial ctr should work fine? so is it that the dpms tube is that bad and out of spec? If i buy a bcm milspec one are they hard to install?
 
Re: Im confused! Need help

The VLTOR tube gives a sloppy fit for some reason. The CTR fits good on a true mil-spec receiver extension tube.
 
Re: Im confused! Need help

Just measure it and compare the measurements to magpuls diagram. That will let you know if it is indeed a commercial or mil spec. Do go by just the slant on the back of the tube
 
Re: Im confused! Need help

Is it possible I have a milspec tube on a dpms ? Commercial tube and commercial stock work but cOmmercial and milspec won't......so by elimination don't I have a milspec tube? That would explain the wobble
 
Re: Im confused! Need help

Get calipers and measure your buffer tube diameter.

My commercial ctr fits great on my dpms buffer.
 
Re: Im confused! Need help

So I measured the buffer and it's a commercial tube ....with a commercial ctr and there is lots of play.... Wtf?
 
Re: Im confused! Need help

Changed my RRA buffer to Daniel defense and can run both vltor emod and ctr stocks on it with proper fit. Change out the buffer tube and if you are running the stock buffer and spring from RRA think about upgrading to the H buffer and new spring. Since I have done that with a PWS break and fail zero BCG the rifle is shooting outstanding and to me there is less recoil in my DI RRA then my Scar 16.
