I was in a similar debate for a higher end semi-auto rifle myself a year ago.
I ended up buying a MSAR E4 in 223 which is a Steyr Aug clone.
Around the same time I purchased the Springfield M1A scout squad, where I mounted a Sadlak scope mount on it and a cheek riser on the stock.
I dont regret any of my purchases but I wouldve done it very differently should I have thought about it more instead of being impulsive.
I wouldve purchased a Les Baer .223 AR-15 and a FN FNAR .308 win. Both are A++ grade rifles for competition or hunting. Very versatile.
My MSAR E4 is a great gun but it is 10lbs for a compact bullpup rifle with a 10+lb trigger pull. I wouldnt take it to war, thats for sure. It 100% needs a forward assist on the bolt. You cannot baby the charging handle at all, otherwise you'll never seat the round. Good point is that it is 1.5" MOA with a 1x-4x scope.
My M1A scout squad is a so-so gun. It will not accept medium loads in 150gr. It just wont cycle. Also since I strapped on a pretty good grade Sadlak aluminum scope mount, every 25rounds or so, one of the brass rounds ejects under the mount and jams the bolt as it is riding forward. Unreliable at best when thinking it is going to save your life in a firefight. BEST accuracy I was able to squeeze out of this rifle was 3" MOA with handloads. If I want it to be a sub 1" MOA rifle, Im going to spend $1,000+ on modifications.
Les Baer threads the rifling on the barrel ONE AT A TIME! thats awesome!
FN FNAR guarantees sub 1" MOA!!!!! Return it if it doesnt!
