Was Hickey's AR15 in burst mode?

The picket fence back then.

Here is a drawing of the 2 shots fired by Oswald at Z123 (ricochet off the signal arm)[edit: it was actually say Z113, the location in the drawing is correct, ie just past the signals, but the time is not correct, ie the drawing says time is Z123 but should say time is Z113] & at Z218 (the magic bullet) & at least 4 accidentally by Hickey at Z313 Z314 Z315 Z316 (AR15 in auto mode)(not in burst mode)(the AR15 (601) didnt have a burst mode setting).

Here in Z313 we see the driver Greer turned around to his right as far as possible looking at JFK's head exploding.
In his testimony he said he was looking at Connally & didn’t see JFK get hit. A lie.  In his testimony Greer thought that Connally was in his usual position in his jump seat behind Kellerman, but in Zapruder we can see that Connally has slumped over to the left so far that it is actually easier for Greer to see JFK than it is to see Connally.  I tried turning my head that far just now & i hurt my neck, i couldnt do it.

However the other pix at Z326 is what i really want to talk about, 13 frames after Z313, ie 13/18th of a second after.
As can be seen Greer & Kellerman have both ducked down as a natural reaction to Hickey's accidental 4 or 5 shot auto burst.
Greer couldnt get any lower & still see to drive.
Kellerman's head is against the dashboard, he cant duck lower.
 
Hickey's shot-1 was at  Z313 (JFK's head explodes)(remnant slug cracks windshield near Greer). 
Shot-2 was at say Z314 (dents chrome trim above mirror). 
Shot-3 was at say Z315 (hits tarmac & kerb Elm St). 
Shot-4 was at say Z316 (hits tarmac & kerb Main St)(Tague stung).

Greer said he felt the concussion of the shots, & there were at least 2, & the shots were almost simultaneous.
Kellerman said that it was a flurry of at least 2 shots.
The AR15(601) was pointed tween Greer's right earhole & Kellerman's left earhole, & the muzzle was only 28 ft away.
If it were me i would have soiled my undies & then ducked.

Did they duck down like that after they heard Oswald's shot-1 at say Z123?
No.
We don’t see them ducking down at Z133 the first Zapruder frame in that sequence (about 10 frames later)(praps 20).

Did they duck down after they heard Oswald's shot-2 at say Z218?
No.
We don’t see them ducking down in frames following soon after Z218.

Yes, Hickey killed JFK.   It was rotten luck, he was just doing his job.

As can be seen Hickey's 601 model AR15 didnt have a burst-mode (ie auto 3 shot burst), hence Hickey must have set it in auto mode (& accidentally fired 4 or 5 or 6 shots) when he took it off SAFE.
It had three settings SAFE --- SEMI --- AUTO.  The Semi-mode auto loads one cartridge per squeeze & fires one shot per squeeze.

Richard Lester in 1974 found a 52 grain deformed remnant of i reckon an AR15 55 grain hollow point slug on the railroad overpass above the south side of Commerce St, buried a couple of inches, between the narrow roadway and the fence, approx where shown by the red star.  This slug might have been one of Hickey's that ricocheted off the road & then curb, or just off the curb.

Lester wishfully thought it was a 6.5mm. The FBI said that it was 6.5mm but had not been fired from Oswald's rifle. Lester believed that the FBI returned a different slug.  I reckon that they were wrong re  the slug being 6.5mm, it was very deformed. And i doubt that 6.5mm slugs can be that small, they are usually around 160 grain. That 52 grain slug doesnt have much missing, it was originally 55 grain not 160 grain.  It had the marks of 4 lands, i havent been able to find out whether the AR15 601 had 4 lands & grooves in the rifling, i think it did. I think modern AR15s have 6 grooves.  The deformation is very symmetrical, unlike a ricochet. Praps the slug hit the vertical face of one of the posts/gaps of the concrete barrier that acts as a fence.

The Lester slug was found at the southern end of the "narrow road" ie footway.  The solid fence on the western side in the pix was back in 1974 when he found the slug just a flimsy open fence i think.  I reckon that in 1963 the slug hit a vertical concrete face, possibly one of the gaps in the eastern barricade.  And it was probly moved by someone or something during the 11 years.

The red line is a possible traject of a slug that possibly ricocheted off the curb 23'4" from the underpass & possibly stung Tague's left cheek.  The red star is possibly where Lester found his slug.  It is a long way south of where it was more likely to be resting, praps it was moved during the 11 years.

Clemon Johnson standing on the underpass saw puffs of smoke on Elm St, not near the picket fence.
