Very good and informative video.  I did well enough in chemistry to do well enough in metallurgy to pass my coursework, but not enough to become a metallurgist.  I sort of regret that.

Timney Triggers has leveraged its history as the oldest and largest aftermarket trigger manufacturer in the world with a new budget-minded AR trigger: The Impact.

Responding to consumer requests, Timney developed its Impact trigger as an option that is uncompromising on quality but is priced right for any budget AR build. The Impact is the latest offering in the company’s People’s Choice lineup of trigger options.

The engineers at Timney devised a way to machine the parts for the Impact from billet steel without resorting to metal injection molding or stamped, old-school parts and assemble the triggers without breaking your budget. Despite the low price of $149.99, each Impact is still hand-tested by the trigger technicians at Timney to get you a crisp and 3 to 4 pound break and drop-in compatibility with all mil-spec ARs.

I have tried neither Timney nor Geissele triggers, but it’s nice to see this kind of competition.

I was talking recently to an active duty SpecOps guy about a build he was doing for someone I know, and I recommended a Geissele trigger (based on word of mouth recommendations).

He complained a bit about the fact that the military still uses the Colt guns with the 7+ pound trigger pull, including him.

If you save and spend your money on good equipment, you’re likely better equipped than the U.S. military.

John Lovell has an interesting video up on AR-15 zero.

If you want more, and a somewhat different approach, Shawn Ryan has a video up of his 36 yard zero and why he does it that way.

MAC continues the BCM AR-15 testing.

I do find his videos very helpful and instructive.

We Are The Mighty.

Ultimately, the decision to shift from 7.62x51mm ammunition to 5.56x45mm came down to simple arithmetic. The smaller rounds weighed less, allowing troops to carry more ammunition into the fight. They also created less recoil, making it easier to level the weapon back onto the target between rounds and making automatic fire easier to manage. Tests showed that troops equipped with smaller 5.56mm rounds could engage targets more efficiently and effectively than those firing larger, heavier bullets.

As they say in Marine Corps rifle teams, the goal is to locate, close with, and destroy the enemy — and the 5.56mm NATO round made troops better at doing precisely that.

I include this not to start another caliber war, but to link up the PDF document, “Rifle Squad Armed With Armed With A Light Weight High Velocity Rifle.”

I had never seen that before and thought readers might find it interesting.

With Chris Costa. I would only find this position comfortable with knee pads.

I found this to be a useful video.  I enjoy and benefit from videos like this where an operation that could be complex is taken apart into its parts and explained thoroughly, with tricks of the trade explained.
