I've been shooting my Colt AR-15 for some time with a 20" HBAR
1/9 twist. My son just bought a used Colt AR complete upper, 20"
HBAR with 1/7 twist for 300.00 at a local gun show an then bought
a new complete lower, folding stock DPMS for 199.00..we were wondering
what some of the pro an cons are...seems I read awhile back that the 1/7
twist has better performance with heavier bullets..?
Looking for some knowledge from you guys....thanks.
