Probably just needs some grease and some firing to break it in.
The button is only good for locking the bolt to the rear when no mag is inserted ...
Spray some lubricant on the mag release spring and be amazed when mags start releasing easily.
Just got mine today and this is the 6th M-305 I have owned and is the nicest overall.
The only issue I can see is that the op rod guide could use peening to tighten it up .
No shims required and the is barrel indexed correctly .
I only took a fast look at it but I feel CanAm has knocked this one out of the park .
ok what the hell my barrel is longer then yours? is that because I bought it with the ammo package?
