Bushnell AR Optics First Strike 2.0 Hi Rise 3 MOA Reflex Sight - $49.99

Yeah that's great if you wanted to ship something out to your friend, I would also choose the 5 to $7 option. But you do realize these people don't work for free and that there's always going to be some amount built in to the shipping to cover Warehouse labor costs. Somebody's got a box up your items and prepare them ship out to you and that person earns a salary so it's got to come from somewhere. I do agree that $17 is a bit ridiculous though

Advantage Arms 1.75-.308 Stainless Steel 7.62mm Suppressor - Black - $239.95

Baffle for bolt printed for semi.
Or have a shitty stamp collection in the safe.
Diligent for baffle
Exigent or ridgeback for print.

That's as good and cheap as it gets. And it's damn good and cheap.
Good times!

Zev Technologies FDP 9mm 7" Barrel 10rd Pistol, Black, Used Excellent Condition - $3324.99

For that price you can get 3 police trade in gen 4 glocks in very good condition. A 17hmr, 450 bushmaster, 308 winchester, 8mm mauser bolt action from different brands, two different ar-15s and a ruger mark iv plus a tx-22 with a frt and 5 mags. I would know because after spending roughly 3000$ on guns in the past decade, thats what I got. Probably some ammo on top as well if you dont include tax. 1000 rounds of 9mm.

Backorder - Microbest C158 HPT/MPI 5.56 Bolt Carrier Group - Chrome - $109.95

Thank you for that link, which I believe is evidence that JJE Holdings owns Toolcraft. That is news to me, and as a 2yro video I should have known. I avoid Youtube so that's not too surprising. Very strange they're not listed. Like you said, that fact doesn't mean PSA makes Toolcraft, nor does it mean PSA makes all the other brands under JJE, or that Kronos Knives makes PSA, etc. I respected Toolcraft's history as a highly regarded OEM provider, far in advance of PSA or JJE, so this is slightly disappointing. I hope the quality can be maintained. As gun owners using a gunsite you have been helpful w/o the attitude. Thank you

Backorder - Microbest C158 HPT/MPI 5.56 Bolt Carrier Group - Chrome - $109.95

6/22/2026 - I'm now convinced that RainbowDiddles is (mostly) correct. The only reason I say "mostly" is because I disagree with the phrase; "PSA makes Toolcraft". And I don't consider that to be anywhere near a big deal .... it's just a minor thing to me.
This video I found removed all doubt from my mind that Toolcraft Inc. is under the JJE Capital Holdings umbrella. I don't know why Toolcraft Inc. isn't shown on JJE's portfolio page ... seems to me it should and would be. Like you, I didn't think Toolcraft was associated with JJE prior to watching this 2 year old video: https://www.youtube.com/watch?v=XQo8UYqMfGg...

Zev Technologies FDP 9mm 7" Barrel 10rd Pistol, Black, Used Excellent Condition - $3324.99

Yeah let's add a ridiculous looking chassis that does absolutely nothing except folds, with bad ergos to a 7" barreled pistol then claim it to be portable, highly discreet and have rapid deployment when any pistol is all of that and doesn't cost $3300 used! This is a gimmick..and an expensive one at that.
