| I have an AR 15 SP 1 Rifle and an SP 1 Carbine. Also a LE6920. Now I believe the SP's will not fire bullet weights heavier than 55 grain, accurately, while the 6920 will handle the heavier bullet weights without problems. Am I correct? Thank You |

Thank You SP1s have 1:12 twist barrel and stabilize 55gr best. heavier ones may not stabilize but some have reported ok results. LE6920 is 1:7 and can stabilize a wider range of bullets. |
