Anyone have experience with it? Considering one for my .22 Avenger ( NOT Avenger X). I question the sanity of spending $200 more on a 6 month old gun that I could not sell for $200. I am seeking a lower Arca rail, but wonder if one mounted to plastic will be sturdy, and if ithe chassis will negatively affect accuracy. The gun is so accurate as is. I shot a 5 shot group of JSB 18.13 grainers last week at .0928 at 27 yards. Upgrade or leave well enough alone?
The purpose is to get a place to mount an Arca rail attachment to use the gun on a tripod. Adjustable LOP is a benefit too-but not at the expense of accuracy.

My kit arrived today. The printing is beautiful, but the install was a PIA. I had all the tools and the Avenger sans factory stock laid out on a thick white towel on my kitchen counter. I ordered my kit without a grip because I wanted an Anarchy Outdoors vertical grip on it. The screw for the grip was in the receiver, the front screw was in a bag. I installed the grip on the receiver before putting it on the gun as I figured it would be easier. Installing the receiver on the gun was tough. It was VERY tight. After about 15 minutes, I finally got it on and installed the front screw. I went to install the buffer tube and could not get the thread to start. I look in the receiver, I see no nut. I took the receiver/grip off completely. The nut was not there. There was no nut on my towel or counter and I vacuumed the whole kitchen. They did not provide the nut.
Jumped in the car and made the 10 mile round trip and bought a 1/4-20 hex nut. Cost-18 cents. Came home put the nut in the hex hole, fought for 15 minutes to get the receiver back on, and the nut won't catch. Took the receiver off the gun and pushed the nut to the rear and started the thread. Fought to get the receiver on again, tightened the receiver screw and buffer tube bolt and the rest of the install went OK. Only took 21/2 hours, just like on screwutube.
I almost took it apart again as the rear of the receiver looks like it's higher in the rear, but I looked at Eustlers video and it looks the same.
Not sure it was worth the time and money until I shoot it, but I do now have a 3 1/2 " Arca rail on the bottom of the M lok hand guard and it seems to work on my tripod.

The good news is that you'll never have to install that buffer tube ever again.

I think I might have went after that receiver with a file to give it a little room around where the safety goes. It's been a while since I did it.

I put it on last weekend and arrived at the same conclusion I did before; looks good, but is a little harder for me to shoot with the accuracy I want. So took it back off and put the wood stock back on.

I just tested it. I do not believe I lost any accuracy, BUT I am now shooting off a very sturdy tripod with the gun attached to it by an Arca rail. I was previously shooting the gun in the factory stock off a very sturdy table using a Caldwell precision turret rest. Although I did shoot a .0928 5 shot CTC group off the table + PTR, I attribute any difference in accuracy to the less stable tripod piloted by a crippled, 70 y/o man who has had 4 eye surgeries. One thing I have noticed, my trigger seems a little heavier than it did before the chassis install. Two 6 shot groups at 27 yards:
