So I got another LE6920, this time an OEM-2, which is great because I wanted to put an extended rail on her and make her into a 'dissipator' style build.

However, the guy I got it from had the shop put furntiure on it, which means - handguard cap and delta ring kit.

Soooo, I guess what I need to know is:

Are there extended rails out there that do NOT have the cutout for the A2 front sight? Everything I have seen thus far that would just 'snap right on' seems to be cut for the A2 front.

Or is this going to limit me to removing the handguard cap (and maybe the delta ring setup) and starting all over from scratch in order to do what I originally wanted to with this rifle?

Thanks folks,

Going to limit you to removing the handguard cap. If I understand your question right. Dissipator's use a full length rifle hand guard.

You might be better off just buying a Dissipator upper complete.

Probably this. Gun shop guy is an idiot, spent a little time and $ defeating the purpose of the OEM 2 only to cause you to spend time and $ un-doing it! How the heck was that config supposed to work anyway with no way to mount a front sight?

See, that's the weird thing - I know the shop he got it from, and they seem to be knowledgeable guys, which makes me think that it had to be something the customer requested... maybe, lol.

Yeah, I was wondering that myself. I cannot think of one logical reason why someone would set this rifle up like that. Very odd.

It makes sense for a lower cost optic only setup.


No reason to put on a rail if you are only adding a scope or red dot. Free float is nice but not necessary for everyone. The fixed FSB is one reason why I am not personally a fan of the ubiquitous 6920.


Not everybody wants iron sights.

I get that but plopping on a longer budget ff still makes more sense (doesn’t have to have rails). Makes no sense for the shop to set it up like this unless a customer asked for it then backed out.

Different strokes for different folks, but for me, EVERY fighting rifle should have backup irons at the very least.

I understand a nice clean build, but having optics being the only sighting option whatsoever on a fighting rifle doesn't make a whole lot of sense to me.

Again, YMMV.

These guys aren't using any.....

^^^^^^
I see plenty of guys rolling w/o 'irons'.

Red Dots and ACOGs, coupled with IR lasers for use under NVGs at night (where they operate a shit ton), irons are just excess weight.

Oh cheese and rice. Them guys ain't real fightin' dudes -- they're just paid actors, mincing in front of a CG'd blue screen, for a new men's body spray ad. Their guns likely aren't even compliant with "The Chart". <<cue the Gregorian chant music>>

Everyone knows that Rambo only had iron sights on all his ARs.

Yeah yeah, poke fun all ya want. : )

I just prefer to have backup irons, sorry.

I plan on just running a good ol PRO in mine, I'm not blessed with as many options as those fellas are.

My rifle, it gets BUIS, no matter what.

However, if you feel that strongly about it, send me the cash to build it, and I'll run it just the way YOU want. : )

/awaits the checks rolling in...

Try a Steiner P4Xi. You will love it. They don't break the bank either.

There are plenty of rails out there that will allow you to attach a free float rail to a standard M4 barrel nut.


If you are careful, you could remove the handguard cap and delta ring by cutting most of the way through them with a dremel. This would allow you to install such a handguard without needing to remove the pinned FSB.

If you have the tools to remove the barrel from the upper receiver, this would open up a lot more options of handguards that do use an included barrel nut.

I am partial to these:

The barrel nut has large wrench flats machined onto it. You do not need a special barrel nut wrench to install it. And the clamping method of attachment means that you do not have to index your handguard by varying your barrel nut torque.

It is a good design.

It has a rail for your BUIS as well.

I don't know why I didn't think of this before.

A Knights Armament RAS would snap right onto that and let you add a BUIS. It would not be a dissipator type setup with extended sight radius though.

You would have to remove the delta ring and handguard end cap, but this would work on your existing barrel nut.

If you do decide to remove the gas block and handguard cap it shouldn't be too hard, since the shop obviously has already had them on and off once.
