Hi,
I was building up my first grendel and have several bolt carriers to use. Is it safe to use a JP enterpises lightweight BCG? Just curious. I would be running just the hornady ammo to begin with.... Best, Daniel |

I'd stick with the standard BCG.

thanks, when i bought it from jp they said the same thing about not using it for 6.8....
but i was wondering since i got the catalog from aa with the order if they use a lightweight bolt carrier in their 5ish pound 6.5 grendel....i guess they dont. i think it is pretty hard to get an ar really light. I bought a busmaster all carbon rifle they listed it as 4.5 lbs and it was actually 5.5 lbs. I put in the jp lightweight carrier and saved 6 ounces, which is about what you save with carbon uppers and lower versus aluminum. |

Then change the timing of your bolt opening just as a heavier bolt group will, but both opposite results of one another. Bolt beat certain areas of the rifle. I use to run a carrier weight but they beat the BCG and the barrel extension. |

Run the heaviest bolt carrier you can find, along with a heavy buffer and an upgraded spring. You will get the best accuracy that way. You want the rifle to be dropping cartridges about 5 to 6 feet from your position standing, so adjust the weight, spring rate, and gas flow accordingly.
