4 flathead screws, two on each side.

Not sure if this is a real question but there are four screws you remove from the rail and the bottom of the rail drops out.

 
Remove the 4 screws holding the bottom rail to the top rail.


Then flip down the tabs towards the front.


Slip on M203. Secure the tabs to the front of the M203 receiver with 2 of the 4 screws you previously removed.

Pretty good price on some RIS II FSP FDE on ebay and this is not my auction.

thanks, yes it was a real question. i remember the screws on the side.
it doesnt work with the 10.3'' correct ?

Correct. Except for that one gentlemen that had a custom 203 job on his 10.3 overseas. There are a couple of "in the wild" pics floating around of it, but I don't have them. Maybe someone chimes in that has those pics? Or more to that story?

This pic?



There isn't much more to it except that the individual is indentified as CPT Joseph "Crazy Joe" Claburn, the CO of C Company, 1st BN, 506th PIR.

That's it! And there is the story.. lol.

And it was in Ramadi, Iraq (obviously ) in 2006.

Those guys were doing operations in ramadi with the 506th, but the guy with that 203 is from SEAL team 3. You can see the seals at about 30 seconds in on this video, and the guy with the 203. Also the guy you see holding the saw on the corner is Michael Monsoor. RIP https://www.youtube.com/watch?v=FavppHXszww

Anybody got a tan Surefire mini they'd want to sell? Still looking for one for my S&S mount.

Filthy...




In a good way of course

Just bought a DD RIS 2 MK18 FSP rail off the EE!!!!!!!!! SO STOKED!

I've been waiting for a m4a1 fde ris ii to pop up. Haven't had any luck anywhere. I already have a fde fsp rail, and Now I want the non fsp.

A legit one? Or a M4A1 chopped down?

Legit one

I have a few questions as most of the pics here are of clones and Block II inspired builds rather than real deal pics. the real pics that are here are buried.

#1. Trigger guards. Are Magpul trigger guards in use and if so, how common are they? Is it an issued item or swapped out by the end user?

#2. Receiver end plates. Are they all CQD or are there standard ones in use also? Are there any with QD attachments rather than the ring for the hooks to rattle on? Same question for the front attachment.

#3. Charging handles. I vaguely remember seeing that both standard and PRI charging handles are used. Are the BCM charging handles in use also?

#4. Grips. Has anyone seen A BCM grip being used or would I be more correct to go with a MIAD?

Correctness matters to me most so I want to get it as close as I can. So far I'm 100% correct so I'd like to keep it that way. (other than the "auto" feature of course)

I'll try and answer this one. To get right to the point it's my understanding that those who use these rifles can pretty much do whatever they want to them as long as when it's time to turn their rifles in they are as issued with the all the serialized parts. As a result rifles "in the wild" are often found in tons of variations with somewhat of an exception to the RIS II rail and SOPMOD II issued optics though as evidenced by stukas87's articles over at defense review we have seen that even these accessories are sometimes removed by the end user. What I'm getting at is that I wouldn't really say there's a 100% correct Block II rifle so if I were you I would feel free to change out the smaller parts that are user preference items such as the pistol grip, stock, etc. because that's what the end users of the actual rifles do as well.  Perfectly as issued would be a different story but it doesn't sound like that's what you're going for as much(and neither am I). To specifically answer your questions, I can recall seeing two pictures where magpul trigger guards were in use. Both were on M4's that still had Knights RAS rails attached but block II accessories and were older (2009 and 2010 I think) As for end plates, there are definitely standard end plates in use. Probably more in fact but it's not really a part I particularly look for in every picture so don't quote me on that. For example these five rifles:



For charging handles while I can't remember seeing any pictures of BCM charging handles (another part I don't really look for), butttt Stukas87 did briefly mention they were very popular on the M4's and CQBR's he was seeing in Afghanistan in one of his articles. For the BCM pistol grip here's his work rifle:



What a fantastic source he is. Reminding me while I'm at it here's the link to his first of three articles on accessories being used by himself and his fellow soldiers overseas which I certainly learned a lot from and found very interesting: http://www.defensereview.com/tactical-ar-15m4m4a1-carbine-aftermarket-accessories-for-military-combat-applications-the-competition-to-combat-crossover/

To reiterate, I personally don't see a problem with any of the pieces you proposed using because once again the guys down range switch their stuff out according to their own preferences as well as they have been Seen "in the wild". Definitely keep a RIS II though Now in an attempt to cover up anything stupid I might of said and provide some real deal pics here's some RIS II FSP love:






This ones wayyyy in the back...




And finally one from surefires Instagram page



Hope I helped.

Mine bent in half  

what doctor mount is that?

Predator Tactical Burkett.

Definitely.

Thanks.

Ken at nitevis has some tan surefire minis on clearance for $230. Tell him Bryan sent you.

Great post

Happy to help man. I guess that was a decent response for being half drunk lol. Also SU231a AND surefire 3p is in the mail. How much y'all think it'll run me to cut the barrel and pin the flash hider?

Finally found a non Fsp fde ris ii rail. Only paid 200 bucks. After looking for 2 months I can finally sleep
" />

Good score. Can I ask where you got it from?

$65 for the cut and $85 to pin a SF3P at ADCO, plus shipping.

Put a wtb ad on texasguntrader. guy was swapping out handguards, and said he'd sell his. Had to travel 1'hour to get it, but it was worth it. Only has minor handling marks

Word that's not so bad. I'll start saving. Thanks for the response and also thank you Iasc300ia I'm glad you think so!

For just a little more cash you can SBR.

I was going to pin mine but after doing the math I decided to just file the form 1, hopefully I can save up enough to do it and get s 556 RC on layaway before July.

I gotcha. That's tempting how much would that run? And how much time haha.

$200 check to the ATF and a bunch of hoops to jump through. It's worth it in the end, even though it will probably add several months to your build. I'm not sure how long the wait is currently. 4-6 months if I had to guess.

I actually have all of my parts now other than the KAC safety, I am just waiting to do the form 1.

I keep my 14.5" barrel somewhere else currently for obvious reasons.

The stripped lower is a Nodak Spud, all other parts (other than the sights, VFG, Sopmod, RIS II and SF3P obviously) will be Colt. Well, I'll also use an SSA trigger.

I know it's been covered/answered, but since you asked, my $0.02 worth.


Even though guys who are issued CQBRs & Mk18s can usually make some minor mods, most mil guys are not gun guys and even if they are it isn't common to see a lot of non-issue mods.  

Everything has been seen in the wild; one can always find/post a pic of any given accessory, optic, whatever, but what you don't see are the thousands of other "standard issue"/unmodified weapons for every non-standard one.

If you want to clone a rifle that is similar to what 99% of our guys are carrying, stick to the basics unless you are cloning a specific weapon you saw (or were issued?).

I know it's not as sexy, and there are better parts/configurations available, but that's not what most guys are carrying (if correctness matters).

Thanks.

After some thought I'll likely go with an as issued look on this one as I'm poor and already have all of those parts.

The biggest deviation I will have is the TA31 ACOG.
#1. Because I want an ACOG and need an excuse.
#2. Because the Elcan is just too far above what I can spend right now.

ETA:  forgot which thread I was in; should read BLK IIs, not CQBRs except it still applies.

I wouldn't sweat the Elcan...mine sits in the cage.  I would try the ACOG before you buy the ACOG; they're great optics but (like the Elcan) they aren't for everybody.  We snagged some T1s out of retro so some of guys were able to replace their EOTechs with those.  The rest of us are still waiting to see what they're going to do with (replacing) our EOTechs.

I really wanted to love the TA31F I had, but the eye relief, and its shortcomings at close distances made me go back to the T-1 on the Block II.
Plus once I put together my SEAL Recce it took the medium/long range role with a variable scope  
If the Block II gets magnification again it's either Elcan or some kind of 1-4 variable.

I tried one out at the LGS, I liked it there but I only held it for maybe ten seconds, not enough time to know if it's for me or not.

I would like a T1 but I already have an Aimpoint on another rifle and would like something different I guess.

A 1-4 isn't out of the question either.

I really liked 1.5-5 on here, the 1.5 was plenty low enough to acquire targets up close, the only thing that has kept me from keeping the Mark 4 on the Block II was the lack of daylight illumination. Indoors the highest setting works pretty well, but outside it washes out. The SPR reticle kind of makes up for it giving you the big circle as a quick aiming point. I'm still debating picking up more glass for the Recce and giving the Mark to permanently to the Block II.

I'm am "the buddy with a gun hobby".

Out of all of my friends, only one has an AR and he built the cheapest one he possibly could.

Looks like I need some more friends.

That's why we're here! This site makes me spend so much money it's not funny...

Freshly painted.  Also traded my brown FDE docter mount for the bronzish one.  Waiting on it to arrive.

If anyone has a Gen 1 FDE/Tan whatever color they call it LMT SOPMOD I'm looking I have a Black Gen 1 I could use as trade as well as a Spare COLT CAR Fiberlite Stock.  Email me if you've got one

Oh and I just filed the stamp on my M4A1 Lower for my CQBR/M4A1 I plan to run both on the same lower and My stamp came in Yesterday on my Surefire SOCOM Mini!!!  I wasn't going the clone route when I bought it otherwise I would've probably gone with a full size tan oh well though

I'm thinking of swapping my CTR for a CAR stock, someone tell me why I shouldn't.
CAR stocks look at home on Block II's.

The only negative imo is the weight. The light stock threw the balance off to me, I also use sopmods which weigh in more than the ctr.

Car stocks do look good though so I say go for it.

Nice paint job guy.
