What do you sight your M4 in at?

[ClackClackBAM]

Hey all, I just mounted my RMR on the gun and was wondering what distance you set it to. I was thinking 25 yards just because that's the most common range I see myself using this gun at, plus adjusting for 100 yards on that setting is fairly easy.

I went with a 50 yard zero using slugs, which felt like a good “general purpose” zero for my Aimpoint T2. A couple of inches high at 25, a couple of inches low at 100 (translation: “minute of man”). This is for my home defense load, which consists of Federal Flite Control 00 Buckshot with some PDX1 segmented slugs on the side saddle. Given how tight the Flite Control stuff patterns, the slug zero works for me. YMMV depending on your preferred ammo.

I went with 70 yards with slugs since that's the longest range I have at my nearby range. Patterning buckshot will depend on what rounds you're using. They'll perform differently depending on your choke and the will of the gods. Crappy buckshot like Remington bulk stuff will print most of the pellets on a B27 size target at that 70 yard range. Running more expensive stuff with flight control results in smaller patterns.

I zero slugs at 100 yards. Allows for sternum hold all the way out from zero to 100.

Got it, thanks!

100 yards with slugs using my RMR. Kinda surprised that the groups were good.

70 yards with crappy Remington slugs, 3 shot group from a Lead Sled. Trijicon RMR Type 2, 1moa dot optic.

 

Another 3 shot group from the same parameters.

Different M4, 3 shot group at 70 yards. Trijicon RMR Type 2, 3.5 moa dot optic. Same cheap Remington slugs.

Hot damn, that bronze is sexy. How much did it cost to get done?

And nice group! Have you found a good place to buy bulk cheap Remington slugs just for plinking?

[StrangerDanger]

Thanks. The slugs were bought during the Obama era at Walmart. Between the slugs and the buckshot, I’d clean them out each trip. 
 

I had the burnt bronze / nickel boron plating done back around 2013 at WMD Guns. I think I paid around 300 bucks back then since I had sent a large batch order of parts. The bolt carrier group and trigger pack were done in NP3 later on. On one of my next painting jobs, I might send the bolt carrier and the trigger frame to have them painted on the visible areas so the snipers don’t get me. the Sync rail should also be painted in burnt bronze. I have removed the iron sights and had the weapon light painted in burnt bronze to match the rest.

Good looking shotgun. Wasn’t thinking of doing anything to mine but now I think I might. Just mounted my MRO last night. Does anyone know if there’s a better pistol grip for this.

hello,new here question for stranger danger, what choke are you using in your m4 for those groups?  if you don't mind me asking. for slugs

The factory supplied Modified choke. I got those groups off of a Lead Sled to minimize shooter errors.

thanks, have had a 870 tactical for a few years, got my m4 6 months ago ,it's just a joy to shoot and i'm 66 years old.. and have a range in my backyard.. live in the woods of northern wisconsin. 

They’re great, aren’t they? Plus you get to enjoy it in a great setting. I’m a little jealous! Post some photos of your range please!

I shot mine last week for the first time and I was very surprised at how well the recoil is managed. I was running high brass magnum slugs that have always been painful to shoot but when I put them through the M4, I hardly felt anything.

On page 65 of the USMC TM 10698A-10/1 it states "it is recommended that the iron sights of the combat shotgun be zeroed at a range of 100 meters with a single projectile (slug) ammunition and 25 meters using multiple projectile (00 or 000 buckshot, etc.).  It is also recommended that three-round groups be fired prior to making adjustments when zeroing with slugs.”

^^^^ This…..

[M2_shootr]

Guess I should add, I mostly keep buck shot loaded. I have shot slugs, I just deal with the sight over bore distance
