BOGO Deal - Buy a SilencerCo Scythe-Ti, get a Sparrow 22 Suppressor - $997.90 + SilencerCo $250 rebate

Sparrow decent can. Mask is better. Scythe has well documented catastrophic failures which is why this bogo exists. How about this. Instead of a scythe I buy a diligent defense enticer sti, a .22 mask have the top two cans for same dollar and roughly same application and don't have one that blows up? Good God sico recall these things.

CZ 75 Pre-B Czech Surplus Pistol 9mm — Numbers-Matching, Grade A - $569 Free Shipping

I'm surprised this hasn't gotten more attention. I had never hears of this store, but I'll be back. They have some great surplus stuff. These are the best condition CZ75 Pre-B models Ive seen in about 10 years. Grade A nickel plated aren't easy to find. Fast shipping as well

HK Rifle G36 16.1" 22LR 20rd Rifle, Black - $359.99

Great 22lr rifle but can't get the flash hider off even after soaking it in PB Blaster penetrating oil and a pair of channel locks.

Black Sheep - 308 Win - 147 Grain - FMJ - $411.80 w/ Code: "GUNDEALS10 "

Some reviews of this ammo state it's consistent but overpriced. For a company that's only been operating a few years their exaggerated descriptions of themselves is pretty ridiculous but I'll try a few boxes and report back.

BOE Suppression IncoLite 9S 9mm Inconel Suppressor - Black - BOE-IL9S - $399

They haven’t shipped and I’ve emailed them twice asking what the hold up is because there’s been no notification it was a back order purchase just like how this post on gundeals says nothing about being on back order.

Archon Type B Gen 2 9mm 4.3" (1)18rd/(1)15rd/(1)12rd Pistol - $599.99

These are available with optics cuts but the price on these is likely due to this version not being the OR model. Threaded barrels are also available, though separately.

And this is a compact, not a full size. The Type A is full size.
