I bought a A 64f in black synthetic and bull barrel about 7 years ago. Good accuracy and will group well even with cheap ammo. once the barrel gets hot the groups will climb about an inch at 100, but very predictably.
Factory mag would cause weird problem like throwing the group off, tried everything , filing the lips, body, ect , finally gave up and just threw it away. problem went with the mag.
Likes to be run wet though,
Might have got lucky with this one , it has been very good and reliable . Have about 2500 rnds thru it so far,
mostly cheap AE or blazer 40 grain
