Good chance you'll be fine as is; you could tweak it up to an H2 or even H3 and an extra powr Sprinco or equivalent.

I have a BCM 11.5 setup very similar to yours and I use a regular buffer spring with a Spikes ST-T2 buffer I also have a Griffin M4SDK also and it work just fine no problems whatsoever. So to answer your question you should be just fine with no alterations to your setup.

My ultimate concern is having a single shot first day of sighting in and no options to adjust reliability on prem. |

Generally speaking, the best performance is obtained with the heaviest buffer and the most powerful spring you can reliably run.
If I didn't already have a given buffer/spring, I would start with an H2 and a Sprinco White (standard) or maybe Blue (enhanced). ETA: your gun is going to run and run fine on whatever is in it; going to the next buffer up or down or the next spring, up or down isn't going to make it suddenly stop running unless you're already at the extremes, like an H3+Sprinco Red...then maybe. IOW, I wouldn't worry about a carbine buffer/standard spring not working; they will. |

Quote HistoryQuoted: Except the Carbine buffer is lighter than the T2 by a material margin. Should I preemptively get an H2 or the likes buffer; maybe even just the Spikes T2? I've never used an 11.5 BCM so not sure how gassy they are to begin with. My ultimate concern is having a single shot first day of sighting in and no options to adjust reliability on prem. |

Okay, good advice gents. To be safe I may buy a couple more buffers with varying weights and also another enhanced spring.

You could replace the buffers until you find the least weight one that locks the bolt back on an empty mag.
