I like the look of the Magpul PRS Lite stock, it mounts pretty solid considering it uses the front qd socket to both lock up in front of the notch on the buffer tube and squeeze down on the buffer tube. It was a little loose for my liking on the Aero Precision buffer tube, not loose where its flopping around but depending on the buffer tube the notch may vary, so what i experienced was with the locking mechanism tightened up the stock would slide about 1/4” back and forth, however you did have to pull on it pretty good to move it. It annoyed me so i cut a rubber shim for the notch in the buffer tube where the locking mechanism sits to take up the slack and it is solid now. Again not a deal breaker as it was but im picky lol.
I decided to install a Magpul B.A.D lever to ease with bolt operation and lock back while on a bench rest.
I made my decision on the Larue Tactical 2 stage trigger over the Timney Impact trigger that cost around $20-30 more. From the info i gathered the larue has a cleaner break and better reset than the Timney Impact trigger although the Timney is supposed to have less creep. But after installing the Larue it feels great! If there is any creep it is almost non existent.
I really like the Anarchy Outdoors precision rifle grip, the shelf on the right side is where you rest your thumb to allow you to pull your trigger finger straight back instead of applying side pressure like you would with a normal ar grip, also the 0 degree grip angle should help with comfort for precision shooting. The grip can also be used like normal as well.
