i will catch a lot of slack for this i know

my first AR was a complete Bushmaster lower and a complete upper from model 1 sales
stainless, 20"bull barrell, 1-8 inch twist rate, chambered in .223 not 5.56
thing was a tack driver
bought a box of remanufactured black hills ammo in 68gr 73gr 75gr and 77gr
77gr was the best, bullets had a high tendency to touch on paper at 100 yrds
the others were ok, usually held a 1.5-2 inch group
the thing was just to damn heavy to haul

so i sold the upper for a pencil barrel 1-9 twist stainless steel 16" barrel from model 1 sales
have yet to really find the top ammo
all the stuff i have been using has performed good at hitting iron targets out to 150 yrds
been mostly shooting black hills blue box in 50gr V-Max and i belive 60gr V-Max
when i get back home i will have time to see what she really digs

also have a 20" complete kit (minus stripped lower) from model 1 sales waiting to be put together
that is a 1-8 twist rate
hoping she likes those 77gr as much as the first barrel i had

all the companies listed above make great products
no arguement there
but there are sooo many manufacturers out there today making AR-15 barrels and uppers and lowers
they all make good stuff to be honest
you can save a lot by buying kits from model 1 sales or del-ton or others
doublestar or stag arms is another manuf. to look at

my last kit i bought cost $800
but it comes with a PSG1 typepistol grip
the really nicemagpul adjustable stock
free floating alluminum hand guard (a must for an AR if you ask me)
20" stainless steel barrel, word on the street is SS is easyier to cut and is slightly more accurate then moly or chrome lined barrels
if your like me and clean your gun after every use go SS
it has a flat top picantee rail also for scopes

i bought my stripped lower at a gun shop
it is a cmmg and is good quality
probably drop a chip mccormick trigger in it, cost $200

so for a G i got a nice AR
if your looking for bare bones open sights you can get one for around $500-$600 total
