AR = Everything

[Tobe_B]

When I setup the LOP and eye relief for me, the ocular was always right over the charging handle.

Unless you have a fixed stock on it, there’s little reason to set your scope up for LOP and eye relief. Most ARs have a multi position stock so that you can adjust your length of pull where needed. Set your scope eyepiece inline or just a touch forward or the charging handle and your issues would probably go away. That’s how I was taught to set mine up by much more experienced guys than me. It’s worked well so far on each rifle I’ve set up.

I agree with this and I’m not sure why it ended up the way it did.
I’m sure there was a reason, but it’s been long enough now that I can’t recall why.

Absolutely.
Not sure why I set myself up for problems.
Been long enough now that I can’t say.

Meh, its easy to do if your used to a bolt gun. These things are just different

Speaking of not wanting to set myself up for problems, how much room do I need to have between the barrel and handguard to run a 3" OTB suppressor (either my Raptor 8 or potentially an OG Triple 6 in the future)? Is a 13" handguard on a 16" barrel enough, or do I need a margin of error?

I bought my first AR-10 a couple weeks ago. Daniel Defense in 6.5cm, a hoot to shoot and if range session one is any indication, more accurate than I expected. Not a light gun, but not ridiculous to carry.

I only have the OG65 to measure off of. It’s a true 4” on the dot reflex from the muzzle crown.
I’m sure the triple 6 will be 3” exactly from muzzle crown. I can’t speak for the raptor reflex measurements, so take the next paragraph with a grain of salt:

I would keep measuring simple, and just make sure from end of hand guard to threaded shoulder you have 3” of clearance. That should give you 5/8” of clearance to the muzzle if things are true and exact.

So for a true 16.0” barrel (but check that it’s not 16.25 or 16.5 etc) hand guard length of 12 3/8” would be ideal.
