My personal TiRANT 9s. I absolutely love it.

Thanks but it sold on 10/10/2013.

The URX 4 has about a 1.56" inside diameter. I have a customer who was considering trying to fit an OPS Inc can inside one. That configuration will *barely* fit.

Got it. He's a good guy. I ask because it is good to know who uses red loctite so when someone sends an upper that requires disassembly, I can plan and even charge accordingly. As you know now, dealing with red loctite is a huge hassle. My list grew today. :^)

pathfinderheli wrote:So my armorer uses red loctite...

Just curious: Who was it?

I used a propane torch... like the plumbers do... The upper and URX are Cerkoted and the coatings held up just fine so I'm assuming there is no damage. Even better. Propane burns a little cooler than butane. I did notice that the barrel seems to fit quite loose in the upper. Never noticed this befo...

Ugh -- red loctite on URXes sucks IMHO. I've applied quite a bit of heat to redloctited URXes in the past and I haven't had any problems. Regular butane torches don't get hot enough to readily melt anodized aluminum. Aluminum oxide has a melting point right around an air butane torch's max temperatu...

I wouldn't pay much more than $4000 for it given that MSRP on a new ER (pretty much the same gun) is $4368.00. SR-25 scarcity might make it more valuable.

Need KevinB or Trey to confirm.

Ya -- I get it. I'm willing to bet it is either phosphate coated or black oxide not painted.

I was wondering this myself, I wonder why they didn't use that green coating like the triple taps. It seems like a standard phosphate type coating to me. I've installed many MAMS and other muzzle devices and it seems like there can be residue from the coating process left in the threads. I don't th...

I don't have a wrench I can rent but I'd gladly disassemble your upper for you gratis if you like. Same day turnaround.

New SR-15 E3 IWS CQB SBR with the URX 3.1:

5.56 MAMS

Does the M4-S require a sleeve and properly profiled barrel as well? I was hoping to put one on my 11.5" barrel and I'm afraid I don't have enough barrel protruding from the rail to fit a sleeve.

The one pictured is from installation. I advised the customer that if it is torqued on that the rifle should be fine but I think he was concerned about the aesthetics.

I have a couple inbound too. $311.25 and I'd be happy to install it for you when it arrives.

I'm a new Ops Inc dealer and I'm getting my first shipment of 12th model suppressors in soon -- the Form 3s just cleared ATF.

If anyone is interested, I'm selling them for $950.00 + shipping to your favorite Title II dealer.

I use a BernzOmatic butane torch . It doesn't get hot enough to damage anything and you can apply direct heat for over 5 minutes. On standard removals (blue loctite) I start by heating the area around the nut for five minutes. And this always works for me. This is a titdbit I learned from Neil @ the...

14.5" mid-length barrel & URX III.

My KAC Shot Show Wish List:

* 10.75" URX 3.1 (extra nice if it could come with the integrated front sight).
* MAMS - 5.56 and 7.62
* 14.5" SR-25 (already dashed on another forum I think).
* A non-QD Aimpoint Micro mount.
