    I commend you on your ability to search and dig up a thread relative to your question. You should have no problem mating in-spec uppers and lowers of different brands. Also, depending on when the lower was made, it may in fact have the normal 0.154 DIA. trigger/hammer pins.

    Buy A Lower

    Thanks for your help! I have figured out all the specs that I want everything to be at I am just not sure what some of the good brands are, I know this is probably a huge debate in taste, style or personal opinion but I from a smaller part of the country and don't have a whole lot to work with here. Plus by the time i spend upwards of 1500-2500 to build i just want to make sure that im using tried and true parts and brands. thanks

    Care to post the specs that you want?

    You're on the right track with the 6920 lower and you have the right mindset on buying quality the first time. I don't know if you're aware but a quality rifle can be had/built for roughly $1k. That's why I'm curious about your specs because $1500-$2000 is a lot to work with.

    I get being from a small area but most local shops aren't going to have the selection of quality brands or competitive price of online retailers.

    Read through the stickied threads at the top of each subforum. They explain what the quality brands are and what makes them that way.

    Buying a Lower

    Sorry that original figure was a little high, but my plan is to hopefully get a complete colt le6920 with the leo markings and more or less a lot of the bells and whistles that i am looking for. I am a firm believer you get what you pay for and more often then not the more expensive something is the better quality it is (of course with all the research of materials and specs used to build, with all the research it takes to make a educated decision). then i hope to get another colt le6920 lower with the same marking both brand new and then finding a really good upper to put on it with a rifle gas system so then i will have a really nice carbine and really nice rifle system. plus the leo markings and all that are pretty sweet and more or less a novelty haha.

    The trigger pins are of the 'normal' size (.155) on all the new manufacture Colt lowers, not .170.

    Go to Grant @ G&R Tactical - he has Colt lowers for sale, as well as complete rifles.

    As far as the LE markings, just get a new model 6920. Really, the LE markings are not something that you want to go out of your way to buy.

    Buying a lower/my specs

    @ eric, i just barely caught that you wanted to know what my specs were. my dream guns consists of a lot of nit picky stuff it seems but i've got plenty of time to figure out exactly what i want; i just want some opinions of people who have much more knowledge than i do on the subject. I would like:

    *either a 4150 steel chrome lined barrel or a cold hammer forged barrel that is MPI'd and in 20"
    *a chrome lined chamber and bore in probably 556 because the tolerances are just a little looser and since i don't want to shoot match grade ammo but would rather just load my own brass and try and find what works for the 1:7 twist rate, it seems they handle the heavier rounds and loads better.
    *m4 extended feed ramps (the good ones)
    *a rifle sized gas system (m16 sized)
    *f marked fsb
    *a3 flat top (im not much for the carry handle and all that jazz and optics seem to work better on the flat top not on top of the carry handle).

    I already am planning on purchasing a complete colt le6920 carbine and then i found another colt le6920 lower that is brand new and not fired that i want to implement all the above specs on and keep the complete carbine probably the way i bought it minus putting new free float hand guards and some sort of optic on. other other good accessories and what not i should look for or beware of?
