pangris · #1 11-07-2023, 12:13 AM

S&W Performance Center 681 Birdsong - This was either 1 of 250 or 1 of 450, chances are the buyer will be able to find their Standard Catalog alas mine is hiding - but - limited and collector type gun. Last one on GB that was LNIB went for $3,125 - REDUCED to $2200 OBO

I've shot and rarely carried this gun, it is mechanically perfect and I hope it goes to another shooter.

Gun came with $20 Hogue rubber grips, I've upgrayydd'd to classier set of classics, comes as pictured with one moon clip.

$2,200 OBO plus actual shipping and insurance to an FFL.

If your state has weird laws, I'm sorry.

Trades considered - Factory Noveske new or used (whatcha got), USO American made optics MOA only, ACOG/VCOG, Vortex Razor optics MOA only

Cash either direction as appropriate on trades, no problem -

I would accept payment over time as long as an initial deposit is at least $750, 3-6 months to pay off, take delivery once 100% paid. I'm not particularly well liked but I'm credible enough and can provide references.

*********************************************

In 2016ish I built these for my twin sons. Both the kids and the guns are mainly identical.

Mega Maten matched sets, sequential serial numbers
Craddock Precision Shilen 16" 1:10 stainless match barrels, .750"
Lancer carbon fiber furniture
Superlative Arms adjustable blocks
Rifle buffer
Gas block measure 9.5" from the beginning of the HG

8 lbs 7 oz as pictured

The good news - Craddock Precision assembled the uppers, low round count, one has about 300 ish one has about 200 down the tubes. Laser beam accurate. The first hundred rounds went really well. Bores look great.

The other news - I've yet to get them to run 100% suppressed. I didn't have a can yet when I got these and when I did buy cans I bought Thunderbeasts with all the backpressure. I think I've had one 20 round mag that didn't have at least one malfunction. I've tried tuning the gas, different mags, playing with springs etc. I've since learned if I had it to do again I'd have gone 18", rifle gas, flow thru cans but I don't have a time machine and I've since built Grendels that are running without complaint.

Differences between them are shooter preferences.

One has a Larue MBT two stage trigger, the other has a White Oak Armament two stage
One has a chromed Aero bolt, one has a bolt Craddock sent me to test and see if the bolt changed reliability
Slightly different rail and sling mount positions
Currently wearing different muzzle devices - I tried an SDN-6 and Dead Air Nomad Ti and it didn't make a difference, neither is a particularly low back pressure as compared to the Beast. Muzzle devices can stay or go depending.

One has the extra hundred rounds because I used with it for a year before we had cans, then turned them over to the boys to find out almost immediately that our new cans made them less than 100%. We primarily hunt pigs on the ground so reliability is our #1 concern.

For the past couple weeks I've been debating throwing more parts, barrels, etc at them and we've decided the Grendels are getting us through the night. We've lived without these in the field for years and my appetite for projects is waning with age.

Comes with one mag each, others available.

So, I'm in them for a hair under $3,000 each.

$5000 for the pair, shipped to your FFL, is my asking price. I'm open to offers.

I hate to split them up but that is my OCD. I recognize that it is unlikely they'll go to the same home.

Not really looking for trades other than 18" or 20" Noveske Grendel barrels, possibly Noveske complete rifles in excellent condition or higher end lightweight 308 bolt guns, threaded 5/8x24.

iRay RH25 or other 640 clip on could be interesting as well.
