A: We're not familiar with BCM's uppers nor this particular round's performance, but we can touch on the subject of barrel twist. In general, a faster twist is better at stabilizing a heavier projectile. A twist of 1:7 isn't the fastest available, and yet in conjunction with a 16" barrel it ought to prove more than adequate to give you rewarding accuracy at the range. Hornady often provides a recommended twist rate for their cartridges, although in this case they haven't. We wish we could be of greater assistance!

A: We think you've got the right idea! A 75 grain bullet falls right within the range of what a 1:7 twist is designed to handle. 68 grains is on the lighter end of the spectrum of what's best for a 1:7 twist, and not ideal.

A: Yes, this is made in Lake City with Lake City brass, but a Hornady bullet.

A: Hi Manual. Unfortunately, the manufacturers list the velocity, but almost never reveal the length of the test barrel. I have tried to contact many of them in the past to find out, but they do not know or seem reluctant to reveal that info. Unless we can find that test barrel data, I cannot figure out the velocity in a 16" barrel. I intend to keep trying and will edit my answer if I am able to get more information. Thank you for your patience my friend.

A: It will function, however the results with it wont be optimal. Being as its a boat tail hollow point round its designed for lang range accuracy and not close range defense. The other factor is that the suppressor will quiet it some but it will still be supersonic. There are very few subsonic loads available for .223 or 5.56x45.
