sahauptman Posted September 3, 2003 Share Posted September 3, 2003 Who makes an 18" HBAR. Lighter then a 20" and should make minor with factory 55gr. Link to comment Share on other sites More sharing options...
Bear1142 Posted September 3, 2003 Share Posted September 3, 2003 sahauptman, Two quick options come to mind. Check out JP enterprises, they have 18" barrels in stock, but I'm not sure about the different contours. You could always get the 20" you want and have it cut down to 18" Erik Link to comment Share on other sites More sharing options...
lucas Posted September 4, 2003 Share Posted September 4, 2003 Go to AR15.com rifles,uppers, lowers forum and see post 18" barrels.Besides JP there are other possibilites.I like the JP.In 18" you can get ultra light or what they call intermediate (L W).

PacMan Posted September 6, 2003 Share Posted September 6, 2003 If you really want a lighter AR barrel, why not just get one in A2 profile? There is a pound difference in weight between the HBAR and A2. I just bought an HBAR from J&T Distributing and had them turn it down to A2 profile for $20 extra.

SJ Posted September 8, 2003 Share Posted September 8, 2003 What ammo has trouble making major out of 16" or 14.5" barrels? M193 55gr should be heading out at about 3050 fps avg out of a 14.5", it only needs 2910 fps right? Anyways cutting down may be cheapest, and the 2" shouldn't make enough difference to cause pressure issues. It would be interesting to see, I like the way the Dissapators look.

rhino Posted September 8, 2003 Share Posted September 8, 2003 What ammo has trouble making major out of 16" or 14.5" barrels? M193 55gr should be heading out at about 3050 fps avg out of a 14.5", it only needs 2910 fps right? That's a good question. I've heard that PMC 55gr is notorious for "not making minor" in 16-inch guns, but if that's true, it's going to be close (or worse) in a 20-inch gun too. I suspect . . . and I could be wrong . . . that once one brand of factory 55gr gets a rep for being loaded light, all of the rest of the factory 55gr get painted with the same brush. Today one of the well known chrono operators was talking about people not making minor with 16 inch guns with Winchester white box . . . now I don't doubt what he says because he's seen it all, but something is odd there. I wonder if MAYBE people are not being specific about which brand of factory 55gr they're using or something when they report it to the chrono people, because Winchester Q3131 and Q3131A should easily make minor out of even a 14.5 inch barrel as you mentioned (they're definitely M193 spec!). IMI M193, So. African M1A3 and M1A4, and all other M193 clones should all easily make it. Of course, there are brands of ammo that print "M193" on the box that don't meet all of the specs . . . I suppose the only way to be sure is to chrono your ammo in your gun and see what's what. Link to comment Share on other sites More sharing options...

rhino Posted September 8, 2003 Share Posted September 8, 2003 Black Hills "blue box: 55gr FMJ did not make minor out of my 16" RRA.-z Black Hills doesn't advertise it as M193 either, does it? I'll bet it would have trouble making it in a 20 inch barrel too. Do you recall the actual velocity from your rifle? Have you tried the Winchester USA white box loads? (Q3131 and Q3131A)?

Zak Smith Posted September 8, 2003 Share Posted September 8, 2003 ~ 2836 fps, for 156 PF. Haven't chrono'd "real" Q3131/A. All I had on hand was the BH and some South African M193. -z Link to comment Share on other sites More sharing options...
rhino Posted September 9, 2003 Share Posted September 9, 2003 Yeah, the Black Hills 55gr is pretty wimpy! If in doubt, go with the 68gr . . . it's a lot more accurate at distance too! I assume the So. African stuff did okay? Link to comment Share on other sites More sharing options...

Zak Smith Posted September 9, 2003 Share Posted September 9, 2003 The South African surplus M193 is very hot, but not so accurate. Pie-plate size groups at 200-yards are common. -z Link to comment Share on other sites More sharing options...

Heck, my groups at 100 yards with a good rifle/ammo combination are plate size or bigger anyway (offhand). Link to comment Share on other sites More sharing options...
SJ Posted September 10, 2003 Share Posted September 10, 2003 Win Q3131A and Federal XM193 should be no problem. They are hot. They're not hot, they're normal. Everything not to spec is weak. Link to comment Share on other sites More sharing options...
PacMan Posted September 10, 2003 Share Posted September 10, 2003 Ok, you're right, ammo loaded to mil spec is considered normal. Can we now say the Ellie McPherson (sp?) "normal" since she's loaded to our specs ? (Sorry if I offend any lady shooters out there) Link to comment Share on other sites More sharing options...
