I'm having a hard time understanding why someone would fuck up a quality 6920 by putting a piston kit on it.
Leave your Colt alone and buy another rifle.
What is your height over bore with the red dot? 50/178 shouldn't be possible.
A 50 yard zero is more like 50/325 with you being 5-6" high at 200 yards.
Here's a 50 yard zero dope chart for 4.25" height over bore.
If it works for you, great. Just not confident your holdovers are what you...
You sure about that? Pretty sure it's physically impossible with a piggyback red dot, unless your primary optic is mounted so low it isn't useable, or you have a rainbow trajectory. You can have a 50 or 200 zero, but not both.
I have a MRDS mounted 12:00 over a 2.5-10x NXS on my AR.
I've shot a lot of 2gun, DMR, and biathlon events with that rifle.
1) Do you find it is really worth it and help that much? you find yourself "you couldn't live without it" or is it a waste?
I love it. I naturally default to the dot...
If the reticle is indeed patented, then there is no need to obfuscate. That's the point of patents: protecting your IP(especially if it is easily reverse engineered).
Additionally, anyone who seriously wanted to "steal" the data could very easily purchase a scope and measure the sub tensions...
I've done stupid stuff like this just for the sake of running timed drills to quantify differences. Shot a whole steel match(rimfire rifle) with an LPVO, 12:00piggyback, and 45deg offset so I could test back-to-back-back
It sold out in about 5 minutes this year. I'm doing the 10k.
Each race is held on a different day. All stages are blind. Camping on site allowed for a small fee.
I'm also in the SE. Hard to find matches. Used to be some good ones in Taylorsville GA but the MD/owner retired. Looks like occasionally there is one at Sawmill and one at Arena.
I have both a Resonator R2 and Turbo K. On an AR I see zero reason to use the R2. The Turbo K sounds the same from behind the rifle and is significantly handier.
On a bolt or lever gun the larger can is an advantage. On a semi auto I see zero reason to use anything other than a K can.
I've actually been in 2 of these that involved shooting from vehicles.
First one was riding in a sxs down a dirt road. You had to engage paper targets as they became visible, 3 hits per in the A/C zone. Rifle only.
Second one involved shooting from a pickup as it advanced on a structure...
