Frame extender/muzzlebrake
Although this is built almost entirely out of carbon fiber, it should be easily copied with aluminum tube. This is designed to fit only a Talon or Condor air rifle, and does not touch any part of the barrel.
As built, weighs 6 oz. and adds 5.5″ OAL to rifle.
Outer tube 12″ x 1.25″ ID. , with bonded “frame to outer tube” adapter. Adapter measures 1.245″ OD .95 ID where it slips into outer tube, 1.009″ OD .75″ ID on small end.
1.245″ OD tube cut into several approximately .25″ long bushings. Several thin 1.25″ diameter rubber washers , hole diameter approximately .27-.3″. Found at Ace hardware in box labeled “fender washers-neoprene”. Much lighter than steel washers, however if more muzzlebrake effect is desired, try adding a few steel washers.
Stack shows 8 washers, as designed there is room for at least 12 before getting too close to muzzle of barrel. More = a more stable muzzle when shooting offhand IMHO.
Endcap made from tubing used for bushings, .5″ long. Aluminum machined plug for end with .266 hole bored through it. (Diameter is a tribute of sorts…)
Cap installed and fixed with a machine screw. All bushings and rubber washers stacked tightly against this cap. (Very tight fit) Tight stack keeps rubber washers locked in place. If not kept tight, the push of air might dislodge the washers.
Last bushing secured with a 10-32 setscrew to keep stack tight.
Finished and mounted. Extremely hush, absolutely NO air noise. Keeps barrel aligned in case of accidental bumping, and I find the gun very well balanced. I have intentionally bumped the muzzle end on walls, doors, ect… and have experienced no POI change. Before mounting the extender, the slightest nudge on the barrel caused POI change. (One very weak flaw in the Condors design).
BTW, please excuse the messy house. Hobbies leave no time for chores.

No, sorry. This design is quiet, but hard to keep in 1 peice. The rubber washers keep blowing out, usually during the shot I needed to hit target and the pellet would make odd whirring sounds as it boomeranged around the forest.

That grip came on the rifle when I bought it. It is an AR15 grip I believe. I am going to mount it on a 2nd frame one day… hopefully.
WOK is making adapters to make fitting these to the rifle a lot easier.
Very Nice. Looks sweet with the CF pattern. If I may ask, what grip is that, would like to procure one of those 😛
Peace,

Are you currently producing these?
the info i get from our local guys is they dont give a crap about air rifles or what we do with them, and as far as shrouds, moderators, ldc’s, pickles, barrel weights, whatever they’re called this week, they better not be able to slip off our air rifle and slip right onto a firearm, so as far as i can see barrel shrouds are fair game?
There is no clear and defined law for airguns that are moderated in the USA.
From what I have read, this mod is legal as long as it cannot be used on a firearm.
Where I live and shoot, I really dont need one. It does add to the “cool” factor though. It also keeps the muzzle protected from damage during handling, which is something I do need. 8)
That looks great! So from my understanding is that in the US you can have a “shroud” as long as it is part of the rifle?
Photobucket hosted video. They changed the format to shockwave after it was uploaded, quality is horrible. Ambient camera noise is loud.

Loudest part of shot is the kodiak hitting the target board 35 yards out.
Interesting note: At around 50 pellets after this video was shot, one of the rubber washers got pulled out of place. Disassembly was a lot easier than I anticipated, just drove the entire stack out of the tube. Reassembled with one slightly wider bushing using the same setscrew locations which tightened up the grip inside. 70 shots now since repair an all looks well.
Wish that I worked somewhere that CF was just laying around. Beautiful work!!
That’s a great set up. It started me looking for left over tubing around the shop. I found some carbon fiber, and aluminum tubing to play with over the Christmas vacation.
I love carbon fiber and have built all kinds of stuff from motorcycle fairings to flat bottoms and chain guards for racing karts, great stuff until you breathe the dust…
Nice work Riff, I like your bipod mount too!!!

Well met bro!
We were building tanks when I started with the company in 2004. I dont even know who the customer was, but I believe they were made for SCBA setups for the fire department. I had very little to do with making them, I was in the tubing section which is the bulk of our business. We only use pre-preg materials these days.
I spent my first year building tubing, my second year finishing parts and running CNC machines. Now Im the production manager and try to keep my hands and lungs out of the way. I am pretty handy at making parts fit together tho. The adapter small end needed sanded to fit inside the large end, and getting the two parts to stay concentric with one another was a challenge.
We have some .5″ thick plates Im considering machining into a buttplate holder. The Morgan I have is nice, but once I adjusted it I never move it. CF seems a better choice.

😯 A carbon fiber guy…. A brother in materials! I read your process piece about building CF tanks, nice work here with the extender…!

That is exactly what I had in mind when I saw the first tubes you posted about! How much $ shipping for some ‘scrap’ tubing like that so I can make one? 😉 😈 😛 😀
Very nice Riffraff.
We understand…. You can not defend Michigan AND have a tidy house soldier !
That is SWEEEEET dude!!!!! So when does production start ? …. LOL
Just for the hell of it, I’d love to see a pic of the whole gun. That decal of what I think says “Airforce Sniper” looks awesome.

shroud looks great in cf for sure.
Might consider stainless fender washers in place of the rubber ones, they are generally very thin and would not add too much weight. Then replace one of the end “spacers” with a softer rubber like a large faucet/drain washer/square profile oring, etc that should give enough “squish” to put some preload on the rest of the stack when securing the grubscrew and keep it all from moving around.
