I talk about how you can tell the difference between a mil-spec and commercial buffer tube and install a Magpul MOE carbine stock on my new DPMS AR-15.

  1. The problem i am having is that i am a larger guy and my "pull" is longer than what the standard Magpul stock will accommodate. This makes it uncomfortable and difficult for me to get the best site alignment on my AR-15. Is there some kind of Longer Buffer Tube or buffer tube extension that i can put on my carbine to make the best and most comfortable use of my optics???

  2. ATTENTION ALL MAGPUL CTR & MOE OWNERS WHO ARE LOOKING TO PIN YOUR STOCK:

    Zero cost, drill one hole, its that simple. Just remove the roll pin holding the plunger assembly. Remove spring and cross bar. Re-insert plunger into stock attached to buffer tube and position length to where you want to pin. Rotate plunger 90 degrees, to where a pre-drilled hole at bottom of plunger lines up to any side of stocks roll pin hole, re-insert pin and firmly tap the roll pin to hold plunger in place. Flip the stock over and use a 3/32 drill bit inserted into the roll pin hole to drill hole into the other side of the plunger. Once hole is drilled, remove roll pin from other side and tap roll pin into the hole just drilled to pin plunger in place. You're done. 

    Worst case scenario buy a new roll pin (3/32 x 3/4) @ $.50 – $.60.

  3. Im totally dumbfounded on what Im doing wrong and not particularly fond on the idea of returning my parts…but I just built an AR15 lower (spikes tactical) and using a new CMMG receiver extension kit [buffer tube] (as far as I know, the CMMG tube is definitely mil spec). I then took my mil spec magpul fixed stock and tried to slip on that stock to my extension tube…the screw holes on BOTH magpul fixed-stock adapters are cut off by the buffer tube's lower adjustment/positional tab area (the lower area of the buffer tube where it slants). Not sure if Im describing this well enough…but long story short, I cant get the screw for my magpul fixed stock to go through to the other side of the fixed stock, because the lower part of my buffer tube is blocking the screw where its supposed to insert thru the fixed stock. I really dont think I screwed in my buffer tube too far either, its perfectly holding the tube retention pin in place. I compared my CMMG buffer tube to my Colt M4's buffer tube and they look identical EXCEPT for the lower part of the buffer tube where the adjustment notches are…the "lower slant" of the CMMG buffer tube looks slightly beefier than the Colt M4 buffer tube. Very frustrated. Any thoughts or ideas? Thank you in advance!

  4. sorry to add on to this but your weapon should always be on safe! gun safety 101 I really don't give a fuck if the hammer has to be back or not for all you people defending him. Clear that bitch and flip your selector switch from semi to safe!
