I just put an 18inch SPR BA barrel on my daughters AR that had a 1-9 twist 5.56 barrel. Went and shot it today put a 1-4 swfa scope on it. Shot some 77 smk out of it. I’m sure with a better trigger I can shrink the groups. But pretty happy with it, paid $189 for it at the lgs.
That's pretty good buddy. If it's a shooter, you can't beat that price. Now you realize, using 77 SMK's is like cheating though.. Ha ha..
I bought these the last time I went to Winnemucca.. Not a bad deal..
