Lilja Short Barrel... New Poll

NFA Disclaimer

Once a sub 16" barrel is assembled into a complete firearm, it becomes a regulated item by the National Firearms Act (NFA), unless assembled into an AR Pistol. Please check with your local and state municipalities for any further regulatory requirements. It is the buyer’s responsibility to make sure they comply with all NFA rules and applicable laws.

Barrel Count
Claimed: 11
Goal: 30 - Need: 20
Deposits: 0

Barrel Length Score
12.5" - 8
11.5" - 7
10.5" - 2

I've asked for your first and second choice of barrel lengths in the spread sheets. I've using a weighted scoring system to determine the winner, possibly 2 winners. Each first choice is 3 points and each second choice is 2 points.

I'm starting a new thread so I can specify the poll a little more. It seems everyone interested in these barrels are interested in getting it black nitrated. I'll still be working to make that happen, but no longer see a need to have it in the poll.

I'll consider each vote a serious potential buyer. If you don't intend to buy a barrel, please don't vote.

I've got the itch for an 11.5" Grendel Black nitrated barrel. PDW/Truck/Tree Stand Gun. However, I'm open to a 10.5" & 12.5" too.

Right now we're looking at either a Lilja M4 contour barrel, which has a carbine length gas system, cut down to 12.5", 11.5" or 10.5" or a scaled down version of the Lilja AR740 contour barrel, with a carbine length gas system, cut down to 12.5", 11.5" or 10.5".

Lilja requires a minimum order of 20 barrels to do this. Obviously I can't make this purchase on my own.

Lilja will have Manson Reamers in the near future and the use of SAAMI Spec Grendel Manson reamers will be a requirement for this purchase.

There's a discount for 5+ barrels and an additional discount for ordering sub 15" barrels. Dan Lilja is ready to quote me a final price once we get him a number of barrels being ordered.

Expect no more expensive than $425 per barrel, and fluting $115 per barrel.

Black Nitrating: It seems everyone is as interested in this service as I am. I'll update the following post with information on this at a later time.

Interested in opinions from anyone with sub 14" Grendels.

SPECS:
Bolt used for Head Spacing - Maxim Firearms 6.5 Grendel Bolt 0.135" recess
Fluted - Optional
Contour - M4 cut to length
Length - TBD
Gas System - Carbine Length
Twist - 7" (subject to change)
Thread - 5/8X24




Timeline:
It's a little early, but I thought it a good ideal to state my goal.

At this time I intend to start collecting deposits by August 1st and would like to be sending the deposit to Lilja by August 15th.

Once details pan out in the next week or so I'll post the order form.

If you're interested in this group buy, please download the sheet, fill out the excel sheet at the link and email it to me at me.cory.m.clark@gmail.com (The email is correct, please copy and paste)

Spikes Tactical Monolithic Upper

I've contacted Spike's Tactical about getting a volume price on their BilletUpper - Gen II - SAR3 Barrel Nut and SAR3 Rail minus the unneeded barrel nut.

http://www.spikestactical.com/billetupper-gen-ii-sar3-barrel-nut-p-1131.html

http://www.spikestactical.com/index.php?main_page=advanced_search_result&search_in_description=1&keyword=SAR3

$30 discount on the rail because of the barrel nut we won't need. As of right now at 5 combos we're looking at a 10% discount, possibly more depending on how many we ordered.

Scratch the 10% discount, we're getting a 20% discount plus a $30 off the rail for not needing the nut for the mil spec receiver.


I've got the setup with the 13.2" rail for my 16" Grendel Build. Here's a couple of pictures.



The upper weighed in at 12.5oz and the 13.2" rail weighed in at 8.3oz minus barrel nut.

Lilja doesn't have the tolling to do the 1/2" twists, so the nominal 7.5" twist really isn't an option here. I wonder what Bill A's opinion on a 12.5" barrel with a 7" twist is.

Has anyone ran a 7" twist Grendel Barrel?

[Castor Troy]

What about 1:8? Personally I'd be using this barrel for 100gr wolf, as I suspect many would

[Bwild97]

I would like to have Bill A. pitch in as well on barrel twist recommendation for a sub 13" bbl. But I would opt for a 1-8" twist with out it.

I don't recall ever seeing any 7" twists in grendel. As far as I know, the 7.5" twist on the 10.5" and 14.5" Sabre barrels are as tight as it ever got. There could be something out there though I guess. Definitely a Bill A. question on whether 7" would be good.

The one thing I can say is that a 7.5" twist stabilizes 160gr. Bullets in my 10.5" barrel. Would an 8" twist do it? I dunno?

You're buying a Lilja barrel to shoot bimetal bullets through? I know it's going to be treated, but most folks would gasp at such a proposition.LOL I like your style! You get two thumbs up!

These are 5.56s in 10.5, 11.5, and 12.5, and I can't remember where I got the photo, but I'm posting it here for reference.

Thanks for the photo! Aesthetically the 11.5" is definitely the sweet spot. IMHO

I should point out that if you look at the Lilja M4 drawing they don't measure barrels like we're accustomed to. They go by the OAL. The industry, as I understand it, is to classify a barrel by the distance from the bolt face to the end of the barrel, due to NFA regs. Someone correct please me if I'm completely off.

The M4 in the drawing shows a length of 17", but for all intents and purposes, it's a 16" barrel.

[NugginFutz]

Cory - you are quite correct in that the common (ATF accepted) means of measuring the barrel length is from bolt face to muzzle. In the case of the 5.56 / .223, measuring from the barrel extension to the muzzle adds approximately 1/2", compared to measuring to the bolt face. I suspect the 6.5 Grendel would be within a tenth or two of that.

I would tend to agree; it just looks "right." Now, should one go with the tech specs one wants or how cool it looks?

Variable (and everyone else) I've been thinking about the lightweight barrel we've been thinking about. I had an AR740 (20") that was fluted. I loved the contour. It seemed plenty stiff. I'm sure we could talk Dan into scaling it down to what we want. Unfortunately I never weighed it. I don't think.
