Need some advice. Got my hands on a factory 12.5 AAC MPW upper and can’t decide what route to go. Obviously the LVAW can is out of the picture but I have an sig srd762 I could use instead but can’t decide on a handguard. The MI handguard is an affordable option but I’m kinda torn because I want to keep it clone but I have the factory barrel still not the stainless that’s been seen with the MI handguard. What do y’all think I should do?

I know someone looking to move their og AAC LVAW can, so if it's something your really after it might be an option. The standard steel direct thread SRD762 is probably the best stand-in because of the tapered rear end, so you're on a good track there. It also feels like these cans would be a good opportunity to get a manufacturer to do a run of clones for us, maybe someone like OCL or Allen Engineering.

The URX3.1 is a phenomenal rail and pretty iconic. If you have a factory upper and already have that rail, why would you want to do anything else other than the original configuration?

Also I forgot to mention the upper I have did not come with the KAC URX 3.1 unfortunately the previous owner sold it which I don’t blame him as they are worth quite a bit. So I just have the upper with no handguard at the moment.

chapman's 14.5 recce had an nt4 and a ff ras. they were chopping the 15.1's specifically for the ops can so you're unlikely to find one with a different can.

The FF RAS + QDSS combo was the standard configuration for all dev recce rifles before they chopped the barrels down, so there's plenty of pics out there as long as you look for the right timeline. As kemp already mentioned, you won't find 15.1 examples because the 16" barrels were cut down to 15.1" specifically to mount the Ops can.

No, the 15.1" barrels were custom for the Navy. MREs were used with standard 14.5" barrels and NT4s

I definitely enjoy that thread, probably where I got the idea from after all the photos of other builds with the flush mounted look

Always wanted to build one. I have a C stamp keyhole upper but was thinking of using my Raised C Cardinal upper.

I usually build clone correct everything but with the Lilia issues I prefer to use a different barrel.  

I found a CLE midlength but was also considering the new Craddock intermediate.   Anybody have a preference on one vs the other on either?

Thanks!

Test fitting:



I haven't been this excited about a build since starting out on my Johnny clone almost 13 years ago.

PRI M84 is on the way. My goal is to have it functional this weekend.

I ordered a mk12 brake and collar kit. This might be a stupid question, but for the NSW do I need to use the included washer and shims in the kit for timing or can I just use a crush washer? For the AEM4 I use a custom collar that Ron turned for the barrel, the brake, and a crush washer. I'm assuming I need to treat this one like a mk12 and use the included parts since the end of this barrel is machined to the same specs. Just making sure. It's not a huge deal right now as I don't have an AEM5 yet and haven't even started the process on one, but I might like to try it out unsuppressed while I wait.

I have a build based on Lilja's NSWC SEAL.  It is stated to be a 16", but standard measurement puts it closer to 17.  Yes, it is carbine gas system, and has a hoggish .080" gas port.  Presumably it was spec'd that way for reliability.  I just run an adjustable gas block under the rail to tame it for the match handloads I shoot.

Lilja should be able to build just about anything you want.  Carson Lilja was very helpful to me.  Lilja's website is showing the 15.1" as "in stock" as of this post.

https://riflebarrels.com/shop/drop-in-barrels/ar/ar15/223/223-8-recce-m4-barrel-2/

This barrel whether buying for building a clone, or for pure accuracy (precision - my reason) will be far more accurate than I can shoot.  The rifle is sub 1/2 MOA with handloads (Berger Match bullets in Lapua bench-prepped cases) and a trigger finger that is up to the task.

Where are we getting clone Colt uppers, preferrable new old stock or otherwise? I want the upper fit to be tight. Otherwise I may get an upper lathed and or loctited. For how much these barrels cost I want it to have a good fit lol.

[Last Edit: medieval_flail][Edited] [#28]


Looking like everything will be correct once I get an upper and decide if I want to give Colt money for a lower. Only issue would be the NXS I have but it's not like NF reissued correct ones anyways.

Just about done with this one- clonish correct- using a Craddock RTR barrel, recent production NF 2.5-10x24, Baldknobber cap with Trijicon RMR, OCL OCM5, H&R lower, G trigger, LMT stock.

Pretty fresh out at the time, the fore end was pretty new on the market, the F-93 was purchased because I had an M93 Magpul that was discontinued, then the Falcon came available.
Just really what I wanted was all it ended up being this.
