CD,

In the picture of the Upper hanging up and being painted -  is this the fed std. 33446 or some other shade? I'm looking for the lighter tan twinge. Thanks

Upper receiver if built by Crane would have either 1000xxx (10.3') or 1400xxx (14.5") SN on left side of upper below the rail.  There's also couple other ways before standardized.  If upper was built by the armorer, then NO extra engraving.  Lower would have M4A1 Carbine striked out and below SN Navy 18-1 in white laser engraved.  Don't have the examples on my phone anymore.

Any mount is acceptable as they are all being used in one form or another. Just go FDE lol.

Thanks i was wanting to do a  640 or 340 with the new swivel mount on FDE just didn't if that would be correct or if I needed an older style. I'm trying to keep them as correct possible as i have plenty of other rifles to put other stuff on.

I'm sure it's been asked and answered many times. Here we go again. I am looking into getting a Colt HRT 11.5 heavy barrel or a Socom barrel with the FSPs and have it cut down to 10.3 and .70 gas port. What would be the best option out of the two? I would be running a RC2 on it. Also who is the most trustworthy place to send it and a guess on cost? Thanks guys.

Better of the two is subjective - but why not just buy an already cut down SOCOM 10.3" barrel? For example: Colt 10.3" SOCOM

As far as the old fashioned method - and no problem if that's your thing - of having a barrel cut down and re-threaded, I would reach out to John Thomas at Retro Arms Works (cost will be between you and him).

Hope this helps...

Ah. In that case, I would just opt for this dude: Colt 10.3" CQB Barrel

Mod0 rocks, btw. But I don't think they were ever configured with heavy barrels. Any particular reason you're looking at an HBAR for your build?

Hope this helps...

@TGWLDR

You ever get one of these?  I jumped on this and received a "its in our shipping department" email the next day, then silence.

Reached out to them yesterday and they said they would get back with me.  Reached out again today, they "over sold them" and my order was cancelled.  Curious if anyone get any or if they realized their pricing mistake and killed the orders.

I was going for the heavier barrel for accuracy and heat. I already have a DD Mod 1 upper. Love it. The MK18 and MK12's are where it's at for me. The information, pictures and knowledge in this thread is amazing. Thank you to the people who answer questions and post knowledge.

Well, I did find a source for the non colt branded Schmid ambi safeties today. I am waiting to confirm they are actually in stock and that my order goes through before I share the link.

Thanks for the reply.

Pics show to be the same style as the colt branded ones previously posted. So, hotdog with a short side also.

(But I am also seeing pics online of both types for Schmidt and Colt semi auto ambi’s. So…. Not sure what I will get assuming they really have them .)

I have the Schmid/Colt on every lower I own. I buy a set or 2 every time I build, they are the same part and the Schmid come with either the hotdog or short for weak side. The schmid can be had for 25-30 bucks or so at ARFTAC normally.

There are several vendors online selling the Schmid Tool ambi selectors. Hotdog lever on everything that I've seen.

They differ from Colt/FN in that the short side lever is just a std lever reprofiled. Also the short lever and barrel interface is different than Colt as is the cap screw.

Example:

I guess I just don't see the difference. I have 2 Colt factory lowers with OEM ambi-safetys on the bench in front of me right now and they look exactly like the pic you posted. Granted these are both relatively new manufacture. Ill gave to go dig thru the safe and find a couple older rifles and check.
Not saying your wrong just sayin Ive never noticed a difference.
