Sounds like S&W is using the Whisper notoriety to sell the BLK. Most people have heard about the Whisper over the years. Not so with the BLK being the new kid on the block.

Hello, I was hoping for some help.
I've been reloading over 20 years. Cast my own heads, etc. I have an old friend who has 2 SSK 300Whisper T/C barrels.That's how I originally was exposed to the Whispers.
My Q. I've been looking at the AR uppers available. SSK is a little out of my price range. Legally I need a 16" barrel. I would like an upper which would shoot and cycle w/ super and sub-sonic loads. Would I need an adjustable gas block to do this? The only SSK Ar upper I've seen (16") had an adjustment screw and block on the center of the gas tube.
I've been leaning toward the S&W upper. Hoping you can guide me in the right direction.
I have Foster neck trimmer/ reamers etc. Plan on using Mil. once fired LC brass. I saw HOSER's thread on brass.
The rifle would be used mostly for paper/ hunting, and sub loads for pests. One of my favorite past times is building accurate loads for a particular gun. Also, What should I get for dies? There are a lot out there. I usually go w/ RCBS but I;ve been looking at the Foster and Reddings.

Thanks for the help, Jason

Chief, maybe. 300 Whisp been around. Have heard things about the BLK in JSOC circles for a while. Don't think it's that new.

Whisper has been around for 20years maybe, but about a year old now for the Blackout

I 'm not new to 300 Whisper. I'm new to the 300 Whisper AR15 upper game. I'ld like advise selecting an AR 15 upper. Looking at the S&W. SSK is a bit more than I can afford. But, if I heard ,"save your pennys kid". I would . I'm looking for accuracy. You got to start some where. I'm not a computer fart. Don't sit here all day. I have a job and have a life. The only other forum I belong to is HKPRO.
I thought this would be a good forum to start before I bought. Now I'm not so sure.

Have Spook build you one is the best advice I can give.

If you want to go the factory upper route, Noveske builds a solid upper that runs. I have not heard any feedback on the S&W uppers so that generally means good things.

Check out CMMGs uppers.

Go with Redding or Forster for dies.

Thank you for the advise. I'll PM Spook. Jason

I wonder if S&W's decision to mark their barrels has anything to do with not wanting to give "props" to Remington. Something akin to their marking all their automatics chambered in 45ACP as "45 AUTO" rather than acknowledge the "Colt" part of the name.

A guess, that's all it is...

If you're looking for accuracy, is that accuracy for a 300-221 variant or accuracy for a an AR-15? There are many cartridges which can shoot from an AR-15 which give better accuracy including the 223. Bullet and load selection of course matters. The 300-221 variants have some useful traits, especially for suppressed subsonics, but superior accuracy and long range are not among them.

Other than 22LR the 300-221 has the least energy of any of the cartridges which are commonly shot from an AR-15. The primary accuracy problems of the 300-221 variants are vertical stringing related to low velocity and and wind deflection related to low velocity and/or low BC bullets. Those aren't caused by rifle,brass, or bullets quality.
