This kit includes an AR grip adapter, MILSPEC Magpul AR buttstock with cheek riser, steel reinforced stock tube, and a tactical tri-rail or M-Lok Handguard. It is original, highly functional, looks slick, and is made in America. And wait, there’s more… If you get all three parts (grip, stock, handguard) a 10% discount will be automatically applied in your cart.
The AR grip adapter comes with a Made in USA matte fiber reinforced MILSPEC A2 grip from White Label Armory pre-installed. It is compatible with AR grips without beavertails. The grip screw threads into a steel square nut inset into the grip adapter. Steel to steel. The grip adapter still allows for easy access to the hammer spring, trigger, and regulator adjustment screws. If you change out the grip, make sure to reuse the included grip screw. It is an M5X30 with M5 star washer.
The stock tube is reinforced with a 1/4-20 x 6″ bolt that threads into a 1/4 inch nut inset into the grip adapter. Steel to steel. It allows for LOP adjustment from 10 – 14 inches. I highly recommend that you get our Magpul MOE buttstock and Riser with this kit. If you are going to add your own buttstock, make sure it is MILSPEC and has the option to add or adjust the comb height so that you can get the right drop.
The handguard has beaucoup room for accessories. It has an integrated barrel band and replaces the stock barrel band. It clamps to the air tube using 3 steel screws threaded into steel nuts for a snug fit. Steel to steel. Choose between Picatinny Tri-Rail or M-Lok handguard. The Tri-rails are a modified NATO pattern and are compatible with accessories that would mount on “21mm Picatinny” “Picatinny” or “weaver” rails. The M-Lok handguard is my personal favorite. It provides M-Lok slots on both sides and the bottom and allows for the most flexibility. You can mount picatinny rails only where you need them and still have a comfortable handhold. Add your own M-Lok mounting Pic rails or direct mount any M-Lok compatible accessory. There are many more low-profile accessories available for M-Lok than for Picatinny as well. The only downfall for the M-Lok rails is that it will cost you a little extra if you want to add pic rails.
This grip adapter will not work with an Air Venturi Avenger bottle conversion kit without modification. We do make an upgraded grip adapter that will work with the bottle kit and plenums. Check that out here: Avenger Tactical Conversion v2
This kit is compatible with the Nova Vista Leviathan as well.
Most of these parts are 3d printed. They can and occasionally do break. Let us know if you have ANY issues and we’ll take care of you! We guarantee your satisfaction or your money back.
For installation instructions, see the below videos. Please note, I no longer sell this kit with the adjustable cheek riser featured in the below video.

Everything fit great and was easy to install. The gun looks and feels very good. If you will just be using this kit on a gun as a bench/target shooter, it will be perfect. We use it for hunting and found some really frustrating issues.
When bipods are mounted on the forearm piece they experience lots of stress when out in the field. They can get bumped, they can be torqued and the forearm piece can break. This happened right away and Buck Rail sent us a new one free of charge. Unfortunately this happened again so I just took that piece off and reconfigured a picatinny rail to attach to the lower air tank.
Because the bipods mount to a barrel band on the avenger, any torsion of the bipods will move the barrel left or right and throw off the point of impact. This happened every time we went out on different hunting trips. We always had to re-zero the scope and sometimes we would get POI shifts in the middle of the trip and miss game. This was frustrating and discouraging. We have spent hours trying to resolve this.
At this point, I have added additional barrel bands and completely isolated the barrel from the bipod mounts and I think this has resolved the problem. But as I said, if you just shoot targets from a bench this kit is awesome. It fits in your hand so nicely and Buck Rail designed it to keep access to the hammer spring adjustment screw without having to remove anything.
In the pictures below you will see how I used scope rings and a picatinny adapter to mount the bipods to the lower air tank. I need to get the gun out to a 100 yard range and put it to a test, but I think this will now provide us with a gun that we can be confident will maintain consistent accuracy.

Had the kit from a major competitor on my Avenger. Was an expensive piece of poo. Broke twice, and the second time was unrepairable. Opted for the Buck-Rail offering as I have, and am completely satisfied with a couple of Terry’s other products. All I can say is WOW, what a difference. Miles above the competition! There is really no comparison when it comes to overall quality and ease of installation. And this kit actually gives access to the hammer spring adjuster.
Thanks Terry. Keep up the great work!

If you are into accuracy, then this Chassy system is a must for the Advenger. It turned my .177 into tac driving sparrow murdering machine.

I have noticed that my previous complaint about the tri-rail in this tactical conversion kit was faulty. Folks let me admit that I was horribly wrong. I failed to realize in the beginning because these items are 3-D printed sometimes the parts do not go on as smoothly as they should not buy a false a buckrail, but due to the fact that not all moldings perform the same way. After struggling with pushing down the travel by hand, I thought about it and came up with a question.: why would it go on so smoothly? I would rather it be a tighter fitting component than being a loose one. I then proceeded to take a block of wood and rubber hammer, and gently knockdown the tri rail into position with great effect, I could not believe how strong the material was that Terry used to make this conversion kit. Nothing rattled. Nothing was knocked out a position. Everything was secure and strong as it should be, my complaint earlier was due to operator error not any fault goes to buck rail. Furthermore, buck rail actually tried to refund me all the expenses paid for both this conversion kit and another kit that I ordered or rather two steel breaches for my Crosman 1377 and my Crosman, 1322. I corrected this mistake by requesting that they cancel the refunds due to the fact that I failed to troubleshoot. I encourage all of you to continue your business with Buckville. They have excellent customer service and stand by their. products. Hats off toto Buckrail!

This is the best kit I've ever bought period! The pistol grip is a must have in my book, can't believe the difference it makes. Looks mean, is mean 👍 Pro tip, paint it before installing it, I did flat black. Another tip, I wrapped a piece of Gorilla tape over the end of the round part of the stock before sliding it on, only covered 2/3rds of it with an 1/8 inch hanging over so it wouldn't catch when sliding the stock on, tightened it up some. When I had it all where it was perfect for my shooting I even wedged part of a cloths pin under the stock, shes not going anywhere now. Very nice work Terry! Now all we need is something to stop the shroud from moving, 3 barrel bands and she still moves 😲 This thing is gorgeous and a tack driver now, Thanks again to all of you! Thank you for your service also, never forget!

My Avenger hollow plastic stock received a well deserved burial in the back 40 as the new Buck Rail Tactical Conversion runs circles around its shallow grave!
I bought the Silencer to quiet the .25 caliber roaring beast, and the front Picatinny Barrel Band, both from Buck Rail, to stiffen the Barrel wiggle. Those turned out as "Must Have" options. Wow! Quiet and solid!
All parts slid on well, or bolted up without any modification whatsoever. I'm more pleased than mere words can express. I mounted an adjustable scope on a see through base, so I could see my low profile picatinny bases, with Glock tritium sights.
Beware bunny hoppers and cabbage rats; there's a new Sheriff in town, and he loves fresh fried hasenpfeffer and bunny stew!

If your looking for a great budget buy to dress up your ava then look no further . Extremely satisfied with quality of kit , the front rail was a bit hard to install and went on easier with a few drops of silicone lube . The grip does seem a bit narrow, it is easily replace with any aftermarket grip if you so choose , but it is comfortable enough and even hollow feels solid . The adjustable stock for that cost , and the rest of kit just can't be beat .
