    Fom what I have seen many people do not, and end up building a different (yet very similar) carbine.

    The AR platform is probably the most modular and adaptive platform available today. I know many people utilize this for their initial setup, and to build a carbine that fits their exact needs/tastes. My question is how many of you use this modularity to utilize a carbine for different purposes, and I don't just mean just switching uppers.

    I'm asking because I have had a bug to build an SPR/Recce type of carbine for a while, which would mainly be for fun and possibly some hunting. I first looked at building a complete carbine, and then at just an upper. Lately I have realized that there would not be too many differences between my HD carbine and the recce I would build. I already have a quality M4 with a free floated barrel and QD accessories. If I purchased a magnified optic and bipod with ADM mounts on both, I could convert my HD gun into a respectable (for my purposes) Recce type carbine in a few minutes. I could also fit all of this in a small hardcase.

    How many of you have gone this route? How many of you have considered this, but decided against it? Why?

    I ask because this just doesn't seem to be very popular, and more uses seem to equate to more (yet similar at the base) carbines for most folks.

    Thanks,
    BINGO...ADM mounts are a large part of this equation. Without true RTZ and fast QDing mounts, the modularity of the AR platform is highly diminished.

    With a magnified optic and bipod...as you stated...in ADM mounts, I can take my HD/PD rifle from this which is meant for CQB/indoors...


    And within a minute take it to this which is capable of easily engaging steel @ 600yds.

That is a lot of costly redundency IMO soley for a nominally different barrel, when I could just switch optics and snap on a bipod.
    OP - I've been debating the same thing recently. Basically the same rifle with different optic. I do not have experience with any QD mounts. I would assume that there would have to be some amount of shift in zero, particularly at distances when you would be using a magnified optic. Maybe that's where a RDS with a magnifier that could either be flipped to the side or on a QD mount would work well, but I was more thinking of variable power scope as opposed to a red dot with magnification.

    I've seen your videos of your 600 yard shots with your SBR. Quite impressive. When you switch between the RDS and magnified optic, do you see much of a shift in zero? Do you get "true RTZ" or pretty close with the ADM mounts? Or maybe close enough for your tolerance.

    I only wish SBR's were legal where I live. You've definitely got a sweet setup!

    That's what I'm talking about.

    You mean I could have just bought one AR and had a couple of different optics?

    Where is the fun in that?



    In reality those 4 ARs are basically the same in terms of rails and furniture. The difference in most cases is the barrel length and material/quality, trigger and optic which leads to changes in operating envelope.

    Thanks pal

    In total honesty I get "true RTZ" from my ADM mounts. I have RDSs that RTZ at 50yds, and then 10x optics that will RTZ at both 100yds on paper, and 600yds on steel. I'm really a big fan of ADM mounts and have been using them for a number of years now.

    every time I try it, I end up spending another $350 or so a few months later and getting a dedicated lower for it... and hence another gun. While swapping upper isnt a big deal, just plain lifting up the right gun is even easier.

    I have some of the same thoughts as you guys...

    My gun hoarding mind wants to have the following:
    10.5" Carbine w/ Red Dot
    14.5" Carbine w/ Acog
    16" .308 Rifle w/ Variable power scope

    While my practical side says stay with the following:
    10.5" Carbine w/ a QD Red-Dot and a QD Acog
    16" .308 Rifle W/ Variable power scope

    For some reason it just bugs me not to have a dedicated intermediate carbine though...even though it's really just unnecessary cost.

    So along with my love for the MRP platform...it looks like I might just end up being a big copy-cat of Trident!

    Trident, do you think the "true" RTZ is due only to the ADM mounts, or a combination of, what I think I saw, the MRP and the ADM mounts?
