I did a search but couldn't find an answer for this one. How much less accurate is a Ciener kit in a 1 in 9 AR barrel than a dedicated .22 1 in 16 barrel like a Bushmaster? Are we talikng only an inch or two difference at 50 yards or are we talking soccer ball size groups? Obviously choice of ammo plays a part in this. Also, does anyone have a Ciener that will feed and shoot Aguila SSS 60 grain?

Here’s how a 1/16 DPMS upper compares with shooting an M261 conversion in both 1/12 and 1/9 barrels. Figure at left is the average of the best five of six 5-shot groups at 25 yards, benchrested and scoped.

.313 DPMS AR .22 upper Winchester Dynapoint (1 of 6)
.350 DPMS AR .22 upper CCI MiniMags (2 of 6)
.392 DPMS AR .22 upper Remington Golden Bullets (3 of 6 tie)
.392 DPMS AR .22 upper Federal Lightning (3 of 6 tie)
.414 DPMS AR .22 upper Winchester XPert (5 of 6)
.425 AR-15/M261/1:12 CCI MiniMags (1 or 5)
.540 AR-15/M261/1:12 Winchester Dynapoint (2 of 5)
.660 AR-15/M261/1:9 Winchester XPert (1 of 5)
.779 AR-15/M261/1:9 Winchester Dynapoint (2 of 5)
.828 DPMS AR .22 upper Federal Bulk (6 of 6)
.848 AR-15/M261/1:12 Winchester XPert (3 of 5)
.855 AR-15/M261/1:9 CCI MiniMag (3 of 5)
.917 AR-15/M261/1:12 Federal Lightning (4 of 5)
1.072 AR-15/M261/1:12 Federal Bulk (5 of 5)
1.673 AR-15/M261/1:9 Federal Bulk (4 of 5)
2.155 AR-15/M261/1:9 Federal Lightning (5 of 5)

As to the Aguilas in a 1:9 barrel, almost every group I shot with them was a 4+1, that is, four fairly tight shots with one flyer. First set of figures below is the whole five-shot group, the second set is the four shots without the flyer. They functioned perfectly in my rifle, but are stinky and expensive and I don’t plan to buy any more of them.
.903 .740 .573 .354 1.152 .625
.542 .364 .236 .354 .513 .431

my dedicated kuhel 1-16 20" barrel @ 50yds holds 1/2" 5 shot groups, with winchester x-perts. using hollow points the groups open up a bit too. this is done shooting from prone with a bipod and 6X Crap scope.
