I'll know Friday morning; that's when I take her to the range and "break her in." [;)]
I went through and cleaned all the grease out of all the components AGAIN, as it appears some grease somehow seeped out. Anyway, the cottle pin that holds the firing pin in place is REALLY TIGHT, and requires pliers to remove and replace. I wonder if that will improve any. Also, the bolt and bolt carrier are VERY TIGHT, and not very free-moving like other AR's/M16's I've worked with. However, since this rifle hasn't been fired, I'm sure after a few rounds, things will loosen up considerably in regards to bolt/bolt carrier fit. Finally, the rear of the bolt carrier is a bit rough, and is really tearing up the buffer assembly's surface, even with just cycling the weapon with the charging handle. Again, I'm sure this will go away after a few hundred rounds, but it's just something I noticed.
Otherwise, color match with my Bushmaster lower is great, and the stock is no longer greyish since I oiled it up. It SUCKED IT RIGHT UP!!! At least now it looks GREAT!
I'm really looking forward to firing her Friday. As soon as I return, I'll post pics and a review here.
