If you are looking for a precision rifle or budget build look no further than the M4E1. Yes it is twice as much as an Anderson lower but here is why.
-Flared Mag well
- Integrated trigger guard
-Tighter lock up with upper
-Tighter spec on trigger pins & selector
-More proud mag release well than regular mil-spec
-Threaded end plate spring, no more shooting springs!
-Threaded bolt release (included screw) If you build lowers you know this pin is very hard to get in with a punch and not scuff your lower
-Excellent hardcoat finish
