Great Duty Trigger. Easy Installation.


I ordered this last Tuesday and received it Friday. Primary Arms is the best. The trigger is very easy to install for a normal guy like me. The trigger has almost no take up or over travel. It feels like 4.5 lbs or very close. It has a very crisp break and a quick audible and tactile reset. It is a great, safe duty trigger. I am glad I bought it.

Smooth Trigger

Bought this trigger several weeks ago and installed it on my Aero M4E1 lower that I put together. I wanted an upgrade from the mil-spec enhanced SI trigger group that I've been currently using. Replacing the SI enhanced trigger to the RA LE145 trigger is a big improvement. I love the short reset and the crisp pull of the RA LE145. I'd definitely recommend this trigger. Thanks to Primary Arms for the awesome price of $116 vs. other on-line retailers who sells them for $134.

Great Trigger and Easy to Replace


I love this trigger! The feel of the trigger is superb. It has rounded edges and breaks crisp and cleanly. I actually prefer this trigger over the Rave 140 I put in my premium build for my long range nail driver. I put this trigger into a S&W M&P II AR and it was super easy and I just love the feel of it. The break is a little bit more than the Rave 140 which is what I wanted in a home defense weapon or a SHTF rifle but it's still a 100% better than the stock trigger.
<br>You won't go wrong with this part so go ahead and pull the trigger and get you one.
