What's an expected precision level with a "reasonably accurate AR"? I have a LMT but really haven't played with it much.
I'm perfectly happy as long as it bangs 30 shots 2" or underWhat's an expected precision level with a "reasonably accurate AR"? I have a LMT but really haven't played with it much.
“Reasonably” is subjective. I would hold it to your whatever standards you have for your hunting bolt gun. An AR can be a 1 moa gun pretty easily. Just don’t feed it junk and expect miracles, like any rifle.What's an expected precision level with a "reasonably accurate AR"? I have a LMT but really haven't played with it much.
Possibly, and I've seen where gas management is important when doing so. Living in Iowa, these are pretty limited to varmint hunting unless a guy gets a 350 Legend or 450 BM upper.Do you plan to shoot suppressed?
I would say it’s just as important to learn how to shoot an AR effectively as it is to have a good rifle. An AR is its own style of shooting, even thought the fundamentals are the same-they are just applied slightly different due to the ergonomics and the fact that its a semi-automatic rifle.
This is also true. The brownels lapping tool is good to use. Takes one minute of time usually to clean up the receiver face.
You can technically bed the barrel extension with red locktite or the like, or use stainless shim stock, but unless you are hand loading to the extreme, you won’t notice a difference if you are using a good barrel.
Also some receivers are a “thermal fit” (like BCM) meaning that receiver is slightly undersized relative to the barrel extension, so use of a heat gun on the receiver to slightly expand it is required to allow the barrel to be installed.
I’m sure there are YouTube videos of all this these days. It’s all super easy to. That’s makes the AR system fun, it’s like legos for adults.

Maybe it’s just me, but I shoot my AR differently than I shoot a bolt gun. The ergonomics are different as is the way recoil is managed, therefore my shooting style is different. Fundamentals are the same, but applied differently. Again, this is just my opinion so take that for whatever it’s worth.How? Is "shooting style" different than shooting a bolt gun in a AR style chassis?
ARs have a longer lock time than bolt guns. Fundamentals of shooting are fundamentals of shooting, but your follow through is more important on a gas gun.Maybe it’s just me, but I shoot my AR differently than I shoot a bolt gun.

I'll be happy with 2" groups.My LMT is a 1.5-2" gun for 10-20 shot groups. I've been feeding it AAC 77gr OTM and AAC 77gr SMK. The DD I had before it was 1.3-1.7", so it was a little annoying that the more expensive rifle was less accurate, but again, 1.5-2 is OK for me.
I often use it as a stand-in for my bolt guns. Most of the drills correlate IMO.
These sub 1" ARs like Ridgeline is building seem fairly unnecessary, but that doesn't mean I don't want one.
What kind of groups were you getting with the Proof barrel? I have thinking of going this route for a while.Great info here - these are the three things I do when assembling my AR precision builds.
Locktite retaining compound is what you'd be looking for - I believe the one I have is Locktite 620.
Lapping is a quick process but well worth it. BCM is the way to go for a thermal fit. Pick up a JP enterprises bolt.
A good barrel is going to be key - Ive had great results with proof research. Expect to spend $500 on up for a good SS match barrel. Carbon fiber is going to be $1000+.
I've done all of this work on previous builds and have seen improvements, with the lapping and bedding being the only work done between testing. Saw a rifle go from 1.7 MOA to 1.2 or so using match ammo.
The biggest improvement will be a good quality barrel. However, the three steps AZ Hunter mentioned are worth doing. If at the very least, peace of mind, at the very best, it ensures that your barrel isnt going to shift on you and has a good surface to be compressed against. I now do this on all of my ARs - my competition AR shoots sub minute with factory ammo
I'm just under 1 MOA with a 20" 6mm arc SS proof barrel.What kind of groups were you getting with the Proof barrel? I have thinking of going this route for a while.
