This is my first ever build, so I have no idea what typical fitment involves. Will I be okay with some hand files and a dremel?

A file is plenty, it is not like you are removing much material to fit the anti-rotation tabs on a hand guard to an upper. Dremels are great tools but can remove more than you need in a real hurry.

I finally opened the box and see that my Mk14 is new production with no tabs, just the screws.

There’s still tabs at the bottom where the anti rotational screws go in right? The top two tabs were gone for a long time. The bottom ones are newer which houses the anti rotational set screws. This will interfere with the upper. Please see my 4 pictures above.

Unless they’ve recently updated the rails to even removing the bottom tabs.

Damn. Yes, the lower ears are there. Mine is in DDC so filing is going to leave them looking ugly.

I guess I should be putting these up on the EE and looking for new handguards :(

My lower receiver arrived today, with a decent scratch on it.

Just not my day...

Do the Aero hand guards fit? Do they come with a barrel nut?

I’m curious to know if the Aero Precision ATLAS R-ONE handguards fit. Does anyone have any first hand information?

Thanks!

Do you own a bandsaw?

Hmmmmmmmmmmmmmmmmmmm. I might have to reconsider my handguard plans... I’m not sure I want to go down the bandsaw path...

Thank you for the information and the picture!

I'd also love some advice on quality FDE/DDC handguards. It seems a shame to chop up good rails. This Geissele set me back a pretty penny!

It's a shame for sure. If it were me, I would cut what I had to in order to make a perfect fit, after everything fit nice, I'd remove it and have the whole thing cerkoted.

Those Geissele are sure nice. I'd love to have one on my sporter.

The Maple Ridge Armoury handguards are quite nice, but I just can’t get past the look of them without the complete/full length top rail.

I’m hoping to make my Modern Sporter and my Stag-10 close copies/clones of each other, so I’m sure that’s going to reduce my handguard options
 
Change of plans here. I was going to go with a light weight 3 gun build but since I already have two 3 gun rifles I decided to build a dream hunting rifle of mine. Ever since I heard about the 7.62x40WT round I've wanted an AR patterned rifle chambered in that round. Now that I have a non-restricted option I'm going forward and building one. Ryan at iBi has been my source for the barrel. I can't wait. Light weight 30 cal bullets in a 5.56 case being shot out of a non-restricted AR type of platform. The round was designed for hogs. Here in NB I'll use it on everyone except moose.
I'll post pics once i get rolling on the build.

You will have to match it to your DDC, the colour always changes.

Is there a brand or type of paint that anyone can recommend for touching up after I file to fit?

I'd prefer not to go the cerakote route since I have a matching Geissele charging handle and even an FDE bolt that's pretty close
 
apologies for not reading the first 139 pages - is there a list of compatible rails available?
specifically i am look at the BCM MCMR or QRF rails (not sure if their anti-rotation piece will fit)

Many options for barrels, we can make a barrel any contour or length or twist you wish, we can also supply Proof or BSF CFW barrels.
For bolts JP seems to be 1 of the best but we are also seeing good success with the Brownells bolts. The JP silent captured buffer system works extremely well but the standard AR15 spring and buffer also will work. The 223 standard buffer system is all that is required.

i dont see why it would be any different than a AR15 spring and buffer, but any experience with the VLTOR/BCM A5 kits?
also, while i have you, any feedback if the BCM MCMR or QRF rails are fitting without modification and/or with the antirotation?

thanks in advance

So maybe this has been covered but to install a dust cover I simply grind off the band so that it can fully insert? Seems straight forward enough
