there is a fellow in the classified section today with three LPKs!
assembling an AR is very easy. and you save a lot of money as well as opposed to buying one.
lets do a run down complete upper from JSE $430 when in stock--
LPK $83 from classifieds--
m4 stock kit $55
out of that you'll need a lower, and some mags there are still some good mags around for say $28 each --expensive but not insane like the $100 prices some places are asking-- you might get lucky and get some mags retail as they do pop up for about retail price of $18 from time to time.
so were at about $560 + 100 for three mags that is $660 + a lower
and the lower is a snag --they do sometimes come up for sale at around $200
sights.slings, free float quad rails and so on all extra price--LOL
so if you build one today with three mags and reasonably good mags --it is probably going to set you back $880-$900+
one of those $500 a1 kits is going to need a barrel --say $160, or does it come with a barrel? then a lower --lets say $200 and mags another $100
so $500+ $200+$100 = $800 that is if they come with a barrel-- the a1 might be the cheapest option.
the big snags are LPKs, lowers, and finding a complete upper in stock anywhere at a retail price.
