Need to order a few more parts for my first build

The optic is a little too far back

I did notice that after these pics. Is there a standard position it should be or do I have to find my preference?

A lot of it is preference, however you most likely are going to be above the mag right before the rail meets the upper receiver.

Maybe I deserve the box of shame but I've never staked a castle nut nor had one come loose on me.

That's because you aren't operating like an operator .

Will hopefully have completion pics by tonight. Rest of the parts are in! Oh and I have to decide on the blue Loctite or staking.

Staking requires a $10 tool from Home Depot and 5 minutes of your time. It's really a no brainer

Or a $6 tool from Amazon (that they sent me 2 of... anyone want one?) 

 

I ended up tightening by feel & staking.

 

I also put that picatinny rail attachment up front (offset) b/c, from when I handled it, that feels like the perfect place I want to index my support hand.

What tool are you referring to?

 

Very nice build btw

I was referring to the spring-loaded center punch. This one from Amazon worked perfectly.

[fatty 241]

Oh that looks pretty awesome lol.  never knew that type of tool existed

 

so you basically jab that springloaded center punch to the corner of the castle nut and it's strong enough to stake it?

 

I've never staked the castle nut as... surprisingly it hasn't come loose even after hundreds of rounds

Its going to take a few jabs to get the metal to move, but it will work.

Make sure you put it on the tightest setting if it is adjustable. And hit it near the middle so you get a good amount of metal to move over.

Both BCM KeyMod grips came in yesterday. Feels terrific.

Excellent work, it looks great.  

[MikeL 3]

Thanks. Shoots great as well! The ACT trigger is great. Love how everything turned out. I "think" I was able to zero the Bushnell red dot as best I can. Went for a 50 yard zero at GFH this morning sitting with a bench rest. I'll go back when the ammo I ordered comes in.

Good placement on the optic. 50 yards is a good zero. Your impact points will be within an inch to inch and 1/2 at 50 yards and 200 yards with a 55 grain bullet.

 

Here is a good article showing the charts with a 50 yard zero...
