I thought have some good-natured fun with my Canadian brothers. We're jealous here in the states that you gents are scoring big time with the affordable Chinese M14 rifles. Just for informational purposes, I thought I'd pass on some fun we had today here in Vegas. :evil:

A gentleman and fellow M14 fan has loaned me a P. A. C. T. model Mk IV timer and chronograph. It is very simple to use. We gave it a test using my select fire NFA Registered Springfield Armory, Inc. M1A rifle.

Anywho, Mrs. Different and I went to the desert today to see how fast "Otto" runs. Otto has been upgraded since he left the factory in 1984. He's outfitted now with a Smith Enterprise, Inc. gas cylinder, chromium plated gas piston, dovetail Vortex (R) flash hider, Sadlak NM operating rod spring guide, CS Speedlock operating rod spring and custom LAW483 M14E2 wood laminate stock.

We also tested Otto with a M14 gas cylinder plug with a 0.040 " diameter hole drilled in the center of the top. I wanted to see if it slowed the rate of fire. Here are the results:

Normal M14 gas cylinder plug: 796, 794 and 805 rpm or an average of 798 rpm

M14 gas cylinder plug with the 0.040 " diameter hole in the top: 755, 764, 750 rpm or an average of 756 rpm

The specified rate of fire for the USGI M14 is 650 to 780 rpm per MIL-R-45012E. Due to the modifications I've made to Otto, I suspect the rate of fire was slightly higher than the specified maximum for the USGI M14.
 
"Good natured"?? We used to have FA shoots but our LIBERAL government several years ago killed that. Shooting FA on a DND range was ok,, BUT DND will not allow civilians on their ranges,, thanks a lot.. Hopefully our conservative government will alter this, with time, meanwhile, the USA is our only access to FA,,,, with exceptions, in the dark of night. Don't vote democrat:50cal:!!!
 
Why waltz when you can Rock & Roll?

A few years back .... wait a minute, make that a few DECADES back ... I had a Genuine M-14 and a Genuine AR-10 that would play R&R.

For me, the M-14 was BARELY controllable with short bursts. Most of the time, I could keep a THREE ROUND burst on a Sil at 25 yds from standing position, or @ 100 yds from prone.

Lonnnnnng burst were fun ... but not real practical.

The AR-10, however, was noticeably more controllable. The straight line stock, pistol grip, and heavy buffer and bolt assembly, made for more control with less fight. This translated into easier/more accurate SHORT bursts, but still, even with the improved controllability of the AR 10, for me, letting rip with a full mag meant I'd better have a BIG mountain as a backstop.

If the M-14 had a proper straight line stock and a pistol grip, this might improve the borderline controllability on R&R. Such a noisy, rambunctious beast would no doubt be great fun at parties ....
