I was hitting 900 yards on a 16" plate with my green bushmaster (first pic in this thread) on Monday. 69g SMK hand loads.

A Guide to Quick-Detach Scope Mounts | RECOIL

Here's an article where the tested zero shifts with various mounts. ADM came second to last with an average of 0.135 MOA.

I had no doubt Bobro was going to be high on the list, turns out to be #1. Too bad they didn't include Geissele and Spuhr.

I've been gearing up to get into long range shooting, but am limited to 300 yards for the most part.

Any chance you could point a person in the right direction for finding a place to shoot long distance?

Thanks!

there was actually a difference between a DMR and SPR rifle at one time.

They've all been replaced by Recces now...

I have one spot that's 900 yArds in tillamook but we don't tell anyone where it is. We had a nice place to shoot in estacada that's 150 yArds and too many people found out and now it's ruined. I think it's even on google maps right now There is always like 30 people there and you cant even get a lane so to speak. . My advice would be to do what I did and look on google maps (satalite). Use the ruler and check yardage on clear cuts. There is plenty of public land you can still go on that has open space. My other advice would be to invest in a good fixed tripod set up. Cause even if you do find a good spot chances are if you lay prone (which is preferable) you won't see over the regrowth and weeds. I'm in the process of building one now so I can just shoot off the back of my truck. Once or twice a yr I drive down toward Bend by myself and find a nice flat spot in the desert and put up my 24" plate at 2800 yArds. I have to drive almost 6 hours to make that trip though. It's like elk hunting. You gotta scout for a good spot. Once you find one keep it to yourself

Very nice!

 

[Saffir]

Very nice!

Thank you! I am one happy fella!

Saffir,
If you find you're having any issues with accuracy at distance, you might try moving the scope mount back fully onto the upper receiver.

I've found that bridging from the upper to front rail can cause accuracy issues unless it's a monolithic upper (rail and upper are machined from one piece).

I took it out to the range last weekend to do some load development and had no issues... 3/4 - 1 moa with my handloads out to 300. It was assembled with painstaking care so as not to torque anything out of alignment on the top rail. So far so good. She's a shooter. Weirdly enough, it won't shoot the BlackHills mk262 mod 1 ammo worth a bubblegum. 1 1/2 moa was the best it did with that but as bad as 2 1/2 moa was experienced! Seems that ammo velocity is in a node that the barrel doesn't much care for. It's fine... I can load better for cheaper anyway.

 

[Mygrainman]

That is an SPR!

He's a happy fella... and I get to start my build from scratch...
not a bad thing though... The best part for me is hunting down all the parts. Gunna be a while since I'm broke and bed ridden for the foreseeable future, but that just adds to the chalange...
I have the barrel, and that's the most expensive/important piece anyway. It won't be a Mk12 mod0, but still an 18" SPR. Stay tuned.
First I'm working on a "mini mark"... a pistol/sBr that takes all the same major parts as @Saffir 's MK12... only smaller. can't wait to shoot them side by side.

Good to know!

 

[BLUE COLLAR IRONS]

I was wondering the same thing, whats a SPR?

Special purpose rifle. Usually a rifle length ar15 set up for long range.
