Looking to buy an M4 and a .22lr conversion / dedicated upper, this will be for training myself before a nice long trip to someplace warm and sandy :)
I am not interested in the "best" rifle, but in the rifle that is closest to what I have been issued and will be using downrange - chrome-lined bbl, M16 BCG, etc. Obviously select fire is not an option right now, but the lower needs to be mil. spec. also if I decide to get my Class III on and buy a RDIAS.
I would like a flat-top, with detachable carry handle (plan on primarily shooting with irons) and a 16.1" bbl with flash hider.
I'm not sure what exactly the pros and cons of dedicated .22lr upper vs. just swapping out the bolt are (other than the obvious price difference) but this is not a rifle or process I want to spend a lot of time messing around with. I want it to work out of the box and not require me to sprinkle it with holy water or spend $200 on gun smithing to get things "running right."
I've looked at the BCM M4 Carbine Mod 1 and it seems to be exactly what I am looking for, any feedback from owners? alternatives? is it quality stuff? How about .22lr upper/conversions?
