Air Venturi Air Venturi Avenger Buck Rail Chassis

[cmatera]

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.

I have my Avenger in It. Love it. Bought the gun used, it came in Terminador stock And moderator. Pretty rough, unrefined 3d printing. It broke in short order. Replaced it with all BR gear. There is no comparison. Buck Rail is the best.

My shooting buddy upgraded his avenger to the buck rail chassis. I bought an avenge-X with tactical chassis. I kind of prefer his.

I'm going to buy it. I appreciate the opinions.

Late to the party. I have one. It looks technicool as all heck, but it makes it a little light for bench rest shooting; I already have the wood stock Avenger. I just recently started shooting again, and I might put it back on.

ETA: It's a no-brainer if you have the synthetic stock version.

 

[cmatera]

I do, and it's a hunter not a bench gun in my case.

Let us know how you like it after you get it set up.

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 was really after the lower Arca rail and that I got. If the gun is less accurate, it will be meaningless and I will take it off, put the factory stock back on and toss most of the BR kit in the trash. Surely not the Magpul buttstock as I have a lot of AR's.

 

[Booder98]

It could just be the weight difference on my part. The wooden stock is a lot heavier than the Buck Rail stock. For Minute of Squirrel (as they say) the Buck Rail is fine, but I'm trying for the smallest groups I can get.

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:

 

[Booder98]

Looks like you're fine to me. You're making me want to spend some $$$ on a good bipod; these Chinesium ones I bought aren't very good.

 

[bivy53]

Wow, sorry you guys had so much trouble putting your guns together. Hard to believe as mine was a ten minute job.

 

[cmatera]

Any time the necessary hardware is not all included, it makes the job much more time consuming. I got the Arca rail I wanted but will likely trash the kit. My beautiful trigger is gone, probably due to the excessively tight fit or some internal interference that I cannot see when the gun is in the chassis.

No big deal, readjust the trigger right? No, it is a big deal. Here is the pic of the trigger adjustment instructions in the Avenger manual:

Note there are 3 holes to adjust the trigger.

Here is a pic of the Buck Rail receiver:

Note the BR chassis only has 2 holes to access the trigger adjustment screws. The rear screw for the trigger is not accessible and is in fact covered by the chassis. I do not recommend this product.
