I started with a Caldwell, magnetospeed v3, labradar, and now the Garmin. The Garmin is the cats meow. No sicking around with aiming or attaching it. Take it out, turn on, and start shooting. Literally that easy.
I bought this a few years ago and have probably used it 6 times for 200 rounds. I just don't have time to reload with 2 small kids at home and it never gets used. Comes with the mk machining powder tip and everything else originally in the box including the manual. My pics have my Facebook user...
I did an origin 300 wsm build last year with a proof fiber barrel, triggertech trigger, Hawkins precision dbm, ag adj carbon fiber stock, and some other accessories for $2900. It's an absolute lightweight tack driver and fairly reasonable...
I've built about 16 ARs the past few years and run the JP silent system in my personal builds as they are all suppressed. I really like the bootleg adj bcg for suppressed as well.
8 cans, including an omega 300 which was my fist purchase 8 years ago, 14 hosts, and never one used an alignment rod and not a single issue. All of mine are qd style and installed per the companies recommendations.
I use larue for my heavier setups though adm makes quality stuff as well. Seekins makes great stuff and aero precision is my go to for lighter cheaper builds.
