    Ok so I see alot of info on LPK's, but the other pieces parts get left off of build plans. Is a mil-spec m4 stock tube, a mil-spec m4 stock tube, a mil-spec m4 stock tube, or are there differences. Also other than the discription of H-buffer and the springs, are the internals of the stock anything to put thought behind.
    I am looking at getting the palmetto state armory lbk, but want to be sure that the tube is a excellent one before I pay a gunsmith to put it on and stake it for me(first build so I am going to have a gunsmith give the whole rifle a once over).
    Are there any other companies that offer a package deal like Palmetto state armory that you guys use?

    There are differences in some milspec receiver extensions...the ones you see selling for $20-$25 are nothing more than "commercial" extensions that are "milspec" in size. I'm not sure what brand Palmetto is putting in their lower build kits. Might give them a call and see who they get the extensions from.

    They're probably not all created equally (although I've never read much on the subject) but if you buy a VLTOR, Magpul, BCM, or LMT complete kit (or any known high quality mfr) you're going to get top of the line. If you are planning on getting, say, a Magpul MOE stock just get the complete kit from Magpul with the tube and such.

    The cheap ones are extruded and the good ones are forged... this can be in either Mil-Spec or commercial dimension.

    There must be a list out there somewhere...

    I have one Stag M4 type and one Stag A2.

    the parts used in the build are
    (1) DSA Inc. 6 Position Mil Spec Buffer Tube
    (1) CMMG CAR Stock Lock Ring/ Castle Nut
    (1) CMMG CAR Stock Latch Plate
    (1) CMMG Carbine Buffer Assembly
    (1) CMMG Carbine Buffer Spring
    the stock it self if MAGPUL CTR, with DD a lpk or MAGPUL MOE with cmmg lpk
    Is it worth while to just buy the kit and replace the buffer assembly and spring, or should I buy the parts seperately and spend more on a buffer tube (better yet how can the tubes differ?)?

    And the brands make a difference? It seems like its just a tube. But I guess I'll spend the extra 20 and get the BCM kit. Now if they only had stag lpks in stock

    Yes the brands make a difference. Like I said the DSA "milspec" extension is "milspec" in size only, not in the material used or the process of making it. Chances are you'll never have a problem with it, but for me I'll stick with a LMT or Colt if I can.
