1200 rpm is just a little too fast

Where you get 1200 from ar15/M16 ?    L7A1 and 2.9oz CAR buffer in a CAR stock ?

These buffer is available from Ken Elmore @ Specialized Armament Sales, scroll down to the buffers

ISMI carbine spring & an H buffer (3.8 oz)...

Just tap the trigger and 10 rnds are down range. Kinda like buckshot

Thx for the link.

If you're shooting 9mm you might try the "Q" buffer as well these are really nice in a 9mm AR/16... in the EE here

also RRA 9mm buffers for $20 here.

Wonder what an enidine buffer would do...

Here's a quick vid of a 9mm AR15 using a standard AR15 carbine buffer spring and an "H" Buffer (3.80 oz).   Chrono average was just under 850 Rounds Per Minute.

This is what happens when you use a 5.56mm H-buffer in a 9mm rifle:

H Buffer Bolt Bounce Failure

Those water jugs had a chance after all

i run the mgi buffer in my 9mm carbine

A little update on my buffer/spring experiment since someone kicked it back up to the top...

A friend and myself were trying different buffer/spring combos to see how high we could get the ROF (Rate Of Fire) from a 9mm rifle. I once fired a Glock 18 and thought it might be fun to replicate something that had a similar ROF (around 1200 rpm).

During our experiment, we found that:

1. Using an ISMI buffer spring w/ standard 3.0 OZ (.223) carbine buffer had the highest rate of fire with a ROF of 1177 rpm (average w/ five BB failures).
2. Still using the ISMI buffer spring and an "H" 3.8OZ (.223) carbine buffer the ROF declined to 1058 rpm (average w/ two BB failures).
3. Still using the ISMI bufffer spring and a RRA buffer 5.6 OZ (9mm) carbine buffer the ROF declined dramatically to 723 rpm (average w/ no BB failures).

1. Using an standard CAR buffer spring w/ standard 3.0 OZ (.223) carbine buffer had the highest rate of fire with an avrage ROF of 967 rpm (average w/ one BB failure).
2. Still using the standard CAR buffer spring   and an "H" buffer 3.8OZ (.223) carbine buffer the ROF declined to 863 rpm (average w/ one BB failure).
3. Still using the standard CAR buffer spring and a RRA buffer 5.6 OZ (9mm) carbine buffer the ROF declined  to 610 rpm (average w/ no BB failures).  

Only the RRA 9mm buffer fired five (20 round) strings with no boult bounce issues.

My unqualified opinion is to utilize an ISMI buffer spring and a RRA 9mm for the most dependable, lowest cost and highest ROF option.

Next month.... The "how slow can we go" experiment.
