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.

I’m very satisfied with how it is easy to use.
Unfortunately the Tri-Rail/Barrel Band was not strong enough and broke, but I would recommend the M-Loc Handguard that was sent as a replacement !
Their customer service is quick and I think they are a trust worthy company, both in terms of their products and their customer service!
Thank you very much!
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.
Needs a cut-out for a plenum extension
The buttstock finishes the look. Very satisfied!!
Thanks Terry. Keep up the great work!
Very happy customer !
Very good fit and finish and a fair price, the Tactical conversion turns the plastic stock Avenger into a totally new and more robust gun . Fast shipping and prompt response to questions via email. First rate company !
Fast responsive service. You can't go wrong buying this.
All the parts fit perfectly and blend together to make the rifle look and feel more solid and ergonomic.
I am very excited to get it out and shoot it.
My only complaint is that the grip that is included is not the most comfortable for my hand, but that is pretty nit picky and a personal preference thing, that can easily be changed out...
Thanks Buckrail!!!
new gun . Fast shipping and prompt response to questions via email , first rate company .
With the conversion the Avenger is much more comfortable to plink with now
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!
Terry knocked it out of the park with this Avenger design! Thank-you for your hard work in creating these awesome stocks!
