Is there a range report on the 308? Was the front end able to keep cool under sustained fire?

No report.  Parts are going to heat treat and then to np3 before I can do any firing.

Looking forward to this rifle in .308 or 300blk. Love the platform just waiting for it to come out in another caliber than 5.56, cant justify another one of these. Hope you beat DMR as I think this will be the better platform.

I just sent some more parts for the 762/308 version to heat treat with some changes that needed to be made.  I will beging doing more testing this week on the 300blk now that those parts are gone.  Juggling a couple projects at the moment while still running production on the 556 model.

I think there are quite a few Squadies, in the US and Brit Military would like one of these?

Just think, ammo right there, M60 case, perfect.

I can't wait! For this gun and for next years deer season.  It'll be so nice to have .308 knock down power in this small of a package while driving swamps & marshlands next year!

I just got parts back from NP3 plating so it will go back together next week and and then more test firing.  I hope to have some video to show by the end of the week of the 308 and 300blk and will post it here.  Been working on a 50 BMG at the same time.  Way to many projects going on in between waiting for heat treat and plating of parts.  I cant just sit still.

Hello, Will you be making the 308 in a longer barrel, say 22 or 24 inches for long range accuracy and hunting?  Even as an option I'd pay a premium for one, it's the real reason for a bullpup in the first place.

Nice I am starting to think I should look at the 308 instead of the 300blk. will this take the Magpull 308 mags? Will standard barrel be 16 or 18 inch

Yes Magpul mags and will be offered in a 16" as shown and then an option for a longer barrel like 20".  I have not decided on the final length for the optional longer barrel as of yet.

. . .  I have not decided on the final length for the optional longer barrel as of yet.

Ken, I offer the following for your consideration:

First, today's typical 16-inch-barreled Bullpup rifle has an overall length of just over 26". That's shorter than a 10.5" SBR AR-15, with the buttstock fully collapsed.

Whereas, the short-compact 16"/26" combo is ideally suited to home defense/other close-in/short-range use, a slightly longer Bullpup platform (30" - 32" OAL) is not a disadvantage, in open-range settings. However, the additional 4" - 6" barrel length launches the projectiles from larger-capacity cartridges at higher velocities --- an advantage in extended-range scenarios.

First, an example of muzzle velocity with an efficient, .308 Winchester-length long-range cartridge (w/ the same 0.473" rim diameter), with a 20-inch barrel (http://www.americanhunter.org/articles/savage-m11-lightweight-rifle) (See Paragraph 3).

Now, considering the potential of your beefy No-more-Mr-Nice-Guy 3-lug triangular Bolt ---



let's compare the muzzle velocity of another efficient, .308 Winchester-length long-range cartridge (w/ 0.534" rim diameter) , with a 22-inch barrel (http://www.nzhuntingandshooting.co.nz/f45/6-5-saum-5152/#post73389).

And, though we're increasing the overall barrel length, to advantage, the relatively mild recoil associated with these two examples cancels the necessity of a muzzle brake, and the attendant additional OAL and weight, "The recoil is very little, like shooting a 243 to me." --- (http://forum.snipershide.info/showthread.php?t=185807&page=48) (Scroll down the Page to Post #2360).

Ken, my appreciation for big-lugged breech bolts intended for auto-loading rifles stems from my AR-10'er days, and my experiments with Eugene Morrison Stoner-designed AR-10 rifles, both, the 1950's Artillerie-Inrichtingen-built Sudanese and Portuguese models, as well as, 21st Century American-built models.

Whereas, the relatively small-lugged Sudanese Model Bolt was susceptible to Bolt failures, during automatic firing ---



the robust design of the Portuguese Model Bolt suffered no Bolt failures ---



The 1991-designed Knight's Armament SR-25 (Stoner Rifle - 25) Sniper Rifle continues the big-lug trend ---



Enter: The 2014-designed K&M Arms 7.62/.308 3-lug triangular Bolt ---



You have my attention!
