Quoted:
I am building a lower for a 16" .300 Whisper that will be used for supersonic and subsonic ammo. I will have a Magpul CTR stock and was wondering what type of buffer and buffer spring you would recommend for this application? I have built six 300-221 Fireball (a.k.k. 300 Whisper)rifles. All of them ran fine running either subsonic or super sonic loads using a standard rifle weight buffer and buffer spring(s). 320pf |

It happens to have a CTR as well. |

What barrel lengths are you guys building? Id like to build one and keep the length, with suppressor, short. Ive got a spare registered lower ready for something.

Mine is a 10.5" Noveske with pistol gas system. Works with subs and supers and with my YHM suppressor it is about the same length as a standard 16" with a flash hider. |

I've got an 8" barrel, adjustable gas block (closed, hi-pressure, and low-pressure) and it works great for my subs (220SMKs subsonic) with and without my 9mm suppressor on. Haven't shot the supersonics yet out of the 8" and probably won't. That is what the 16" is for :)
