I try to keep dedicated Bolt/Carriers with each of my uppers but it probably isn't necessary. The 223 Bolt/Carrier will work woth a 300 Whisper and I would still suggest you check the headspace but it should be fine (You can use a 221 fireball headspace gauges).

As for the barrel, SSK is the only place to geta real 300 Whisper and while SSK is more expensive their product is unquestionably the most accurate and best plus it pays SSK for their work to create this concept. Beyond SSK, I feel the better of the affordable barrels are from Model 1 Sales (300 Fireball). You can also have most any good AR-15 gunsmith turn you down a .308 barrel blank to any length and profile you desire and chamber it for the 300 Whisper. Just remember you want a 1:8 twist barrel if you want to shoot subsonic loads. The slower 1:10 twist barrels will not work well with the heavy bullets!

Note that I personally have not purchased a thing from Olympic Arms for the past ten years when some IDIOT at OA talked down to me on the phone almost 10-years ago. I was working on getting an OA 300 Fireball upper to run and these idiots informed me I was not capable of working on my upper and they do not support their 300 Fireball products. Pissed me off a whole lot and they don't deserve my money and for most of 10-years I have not owned a single OA product even though there are a few on this website that others own.
