The Rock River Arms Lower Receiver Parts Kit is the perfect addition to any AR-15 build. This kit includes all the necessary parts to complete your lower receiver, including the popular National Match 2 stage trigger and a standard A2 grip for enhanced accuracy and control. This kit is made from high-quality materials and is compatible with most AR-15 builds, making it a versatile and practical choice for any gun enthusiast.

The National Match 2 stage trigger is designed to provide a smooth and consistent trigger pull, allowing for greater accuracy and precision when shooting. It offers easy, drop-in installation for all MIL-SPEC lowers and comes pre-adjusted by RRA's gunsmiths. The MIL-SPEC A2 grip is ergonomically designed for comfortable and secure handling with a single-finger groove and textured checker sides.

Note: Rock River Arms National Match trigger pins are .1555 in diameter and it's recommended not to use with .154 pins or .170 Colt lower receivers. RRA's .1555 pins fit any standard MIL-SPEC lower without modification, but are noticeably more snug than .154 pins.

 

Features:

  • 2 stage trigger for improved accuracy and precision
  • A2 grip for comfortable and secure handling
  • Includes all necessary parts for lower receiver assembly
  • Made from high-quality materials for durability and reliability

 

The Rock River Arms Lower Receiver Parts Kit with 2 Stage Trigger and A2 Grip are a must-have for anyone looking to enhance the performance and accuracy of their new AR-15 build.

rra 2 stage trigger lower kit

by

all componets went in perfectly in my dpms lower

The trigger and service I expected

by

As I've come to expect, the speed of service from Primary Arms was exceptionally quick. The LPK delivered was extremely high quality, and everything fit perfectly. The Rock River two-stage trigger can't be beat. It delivers 90+% of the performance of a Geissle for what? Perhaps a third the price? The only think I'll say that perhaps could be a ding on the RR LPK is that all the rest of the parts just came in a bag. No instructions except for the trigger, and no explanation of what part was for what purpose. Compared to the CMMG kit I got, which had the parts on a card, with the part names printed on it. Made the build with the CMMG, my first, quite easy. But in all other respects, the RR was slightly superior. Except the trigger. I love the RR 2-stage trigger!

nice trigger kit for the price

by

RRA Lower parts w/2 stage trigger

by

Great deal. I wanted to compare my Geissele 2 stage trigger with the RRA. Very close indeed. The price is right. 90% of the trigger for less than 50% of the price.

A lower parts kit with a really great trigger!

by

I had to call up Primary Arms to doublecheck that this LPK indeed had the same two stage trigger they sold separately, as it seemed like such a deal.And it was. The LPK is pretty straight forward and standard, but the two stage (National Match) trigger came with a great little documentation leaflet explaining its installation.I really appreciate the slack you pick up when you slightly pull the trigger and knowing exactly when the hammer will be engaged.

Rock River parts kit with two stage trigger

by

I have put together numerous AR's and have to date found no other parts kits of this quality. This kit was assembled on a Rock River lower and went together with all parts fitting very precisely, yet pins all started easily and springs fitting their various tunnels without having to open them up. The two-stage trigger is amazing, The trigger and hammer pins fit the frame tightly,with just the right amount of gentle persuasion with a small gunsmith's mallet to assure a snug fit. I'll be looking to Rock River for the kit and trigger for my next AR build!

RRA two stage trigger

Not only an I very impressed with Primary Arms lighting quick shipping and quality merchandise. There installation video was top notch. I have been an avid gun owner for many years but this is my first attempt at building an AR style rifle. Pricing was inline with anyone else online. I will be purchasing other items from them and recommending them to my friends. Way to go PA keep up the good work.

Dependable
