A buddy ask me if the new AR15/M16 if it has the same twist as back in the day? A dose it matter? TY
Ty, I hink That guy Will on that show where he builds guns in Louisana said there is a difference, but not enough to make anything out of it. I personally do not know. So I guess I should not have answered huh, no help right. JLC
it was 1.9 and now 1.7 for the different barrel length....
for bullet stabilization. On average 1:9 will be fine for 55-69 gr. give or take. If you're shooting heavier bullets like 75 gr, 1:9 will still work, but ideally you'll want 1:7 (or at least 1:8), especially if its a precision gun.
Faster twist = heavier bullet stabilization. Slower twist = lighter bullet stabilization.
do all the maker make it that way? TY
i think i remember hearing they had a 1:12 rate at the time they were first made.cant say for sure,since ive never seen one with that twist,and just cause you read it in a book or on the net dosnt mean its true.
Yes, you can still find 1:12. I don't think it was mil issued, but not positive. I probably wouldn't go over 55 gr in a 1:12.
Tallguy- 1:9 used to be the standard for most manufacturers, but more and more are starting to make 1:7 because of demand for shooting heavier bullets at longer distances. ebear is a flamer.
I guess early issued M16A1's were 1:12 and some were 1:14... still not positive. Now everything is 1:9 or 1:7 tough.
thanks for the clarification.the ar barrel i have is a 1:9,since its only a for fun gun,and a little coyote/bobcat shooter i figured it would work fine.55 gr fmjs are more accurate out of it than i would have thought.no problem hitin water bottles at 100+ yds with open sights.still needs a scope freefloat handguard installed,and backup sights,it should be a fairly good shooter after im done.65gr should work ok with that twist too i think,havent tried yet though.
I usually run 55 and 62 gr through my 1:9. 65 gr will be fine.
If u say so Reaper but I never will :>)
hell he announces it!!!!
I mean hell, you fart and he bats his eyes!
maybe dats y my shorts r brown not white u think?
