It's Begun

[Artful]

found gentleman who has 300 Whisper 1:8 twist Carbine barrel from ER shaw, so sending the money Monday :nanabang: -

Now to start looking at upper's - wish me luck :rolleyes:

[Cornholio]

Good luck. Do you have your reloading stuff yet?

[Artful]

Nope that's also on the list. And brass and I'll have to order in some selected bullets SMK 220 but I have been lookin for the barrel for several months - ACC Cyclone on order but that will take several more months so I have time.

Patience is your friend when you don't have large amounts of disposable income. ;)

[speed]

What is an ACC Cyclone?

[Artful]

ER Shaw Barrel is here - 16 1/4 long 8.75 under handguards .75 stepdown for gas block in carbine position, step down to 7.25 until last 3/4 inch then step down to .700 until threaded for final .6 inch w/ 1/2x32 it appears.

Heavy little begger. Was over on another board and posted this Thread about a piston upper...

Stupid question if I get a 300 whisper barrel can it be used on your piston upper?

And would it make more loud noise as it's tapping high pressure gas to drive the piston then dumping it into the atmosphere...or does it have a gas cutoff to keep un-needed gas from escaping ie weapon noise that the suppressor can't eliminate...

And good photography and nice subjects too.

So that's the next step after I save up the money... :rolleyes:

Advanced Armament Corp makes the AAC Cyclon is a Muzzle can for .30 caliber weapons.

http://www.advanced-armament.com/products/rifles/cyclone.asp

Fluff from their site

The CYCLONE is a thread-mounting silencer for 7.62mm bolt action and semi-automatic rifles. Constructed entirely from welded 300 series stainless steel, the 8.38" Lg x 1.50" diameter CYCLONE is the most compact and durable 7.62mm rifle silencer on the market. The computer optimized baffle stack of the CYCLONE delivers a substantial frequency shift, and the resulting muzzle report is indistinguishable from the ballistic crack of the projectile in flight. The weapon's flash signature is completely eliminated, and recoil is reduced to the extent the shooter can actually see bullet impact through the scope. The slight added weight of the CYCLONE will assist in reducing barrel harmonics which can equate to a significant increase in accuracy with many host-weapons. Delivered with standard 9/16-24 threads, the CYCLONE is available with other mounting configurations upon special request.

FAQ
How does the Cyclone mount to my weapon? Via muzzle threads.

Will the Cyclone work on my .300 Whisper? Yes.

What different threaded mounts are available 9/16-24TPI & 5/8-24 TPI. All barrels must have a minimum muzzle diameter of .600”.

Will the Cyclone affect the accuracy of my rifle?
Yes. The slight added weight of the Cyclone will assist in reducing barrel harmonics which can equate to a significant increase in accuracy with many host-weapons. There will be a point of impact shift between the rifle with and without the silencer, but it is a repeatable shift.

How do you clean the Cyclone?
The Cyclone can be cleaned through periodic immersion in a suitable solvent (IE. lacquer thinner).

How often do you clean the Cyclone? Every 2000-3000 rounds.

Can I shoot full auto through the Cyclone? Go ahead, you won’t hurt it.

Can I use the Cyclone on my belt fed?
Yes. Just check frequently that the silencer stays tightly threaded to the muzzle threads.

Can I shoot .223 through the Cyclone? No problem sound reduction but not as good as 30 caliber but you shouldn't need hearing protection.

Can the Cyclone be used wet?
The Cyclone can be used wet. However, when using a wet can on a gas operated weapon, the gas system will become fouled with sooty, wet material after repeated firing with water in the silencer.

Service Life? Unknown, as no one has worn one out at this time.

Subsonic load
unsuppressed 156.8
w/ AAC Cyclone 126.3 - reduction 30.5 Dry - and that's with 308 Subsonic
I figure the Whisper should be better as I doubt it's 156.8 unsuppressed.

Now waiting for the bizillon months for approval until my Cyclone gets here but that give time to assemble and test the upper without the can to see if it really does tighten groups like some have said and have repeatable Point of Impact shift.

:D

[Artful]

Cyclone is at my dealers :nanabang:

Now have to go over and get all the paperwork started - get pictures and prints and then get that puppy transfered to me. ;)

Have you taken a look at the Leitner-Wise piston conversions? The L-W system is self regulating and it only takes a fraction of the gas that a direct impingement system does. Here's a link to a great explanation of how this system works: Link (http://ar15.com/forums/topic.html?b=2&f=171&t=148281)

I'm getting whisper with this system in the next few months. I hope this helps.

Hey thanks for the link, I have not settled on which upper yet, tried to order a Adjustable gas tube from brownells but it was out of stock. So I will keep saving until either I can afford a piston or brownells gets me the cheap starter version. :D

[zunrj5]

Artful,

Have you decided on optics yet? That's my next move. I'm looking a some of IOR's stuff right now as I like their MP-8 reticle. Good luck.

Well I got a 6x20 42mm obj w/ target knobs and mil-dot but I'm not sure that will stay for the project - I tried on my AR w/ 223 and wasn't that happy with it there (used it for precision rifle class out to 300 yards). I'll keep playing with it until I get my Whisper AR built and try it again but I was looking at some of the other toys people had and may rethink - too many choices in life.

Problem I have is Bad/Old eyes and things that looked good way back then don't look as good now so I'm looking for all the cheatin I can find. And those red dot sights spoil you, I'm stating to think of those for everything from Air rifle up to Hand Cannons. :rolleyes:

[Artful]

Well, closer - barrel is in the upper with free float handguard - need to dremel the M4 ramps and it will be all set. Now to start saving for reloading dies and brass - Starline says maybe middle of '06... May have to start with someone else's brass for now - but first to get those ramps done.

[Artful]

Redding Dies - 221 Brass - little time and 200 300/221 Fireball ready to load - have a few 30 cal pulled military 163 grain FMJ flat base bullets so will try these first - Thinking full power super sonic load work up first then go down to subsonic with them.:sniper: :nanabang:

Still waiting on clearing pprwrk for the can.
