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 4.3" 9mm (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.

Panzer Han9 6.5" 9mm 30rd Pistol MP5 Compatible with Flip Up Sights - PAHAN9PCCB - $499.99

While initially I thought this was a deal however after shopping around, I have realized that this is the normal regular price that plenty of other sellers are selling for. Gunprime charges $29.99 for insured shipping.
The link below is the same price for the pistol BUT has free shipping, saving the $29.99 fee at gunprime

Hi-Point HP-15P Gold 5.56 NATO 10.5" 30rd - $649.99

Why would you pay so much more for a gold colored model when the black model is almost $200 less? Especially one made by hi point...

Buffalo Cartridge Co. 9mm BRG9 Elite 4" Barrel Grip Safety Trigger Safety Ambi Mag Release 2-16 Rd Mags Feature Rich Black - $199.99

$200 for this pistol is a fantastic deal! I own one of these and overall it is a good gun. It's reliable and plenty accurate. It reminds me of a Springfield XD crossed with a glock 17.
It's the perfect truck gun or nightstand pistol. Slap a nice inexpensive light or light/laser combo and you have a good home defense weapon. I've probably shot 700-800 rounds of various types with very few issues
The only few hiccups I had were with the magazine. If I have a gripe it is with the mags. They are very cheap plastic and have pretty weak springs. But overall for $200, you can't go wrong.

Mossberg CBC 715T Tactical 22LR Semi-Automatic Flat Top Rifle with Red Dot - $269.99

At first glance this may look like a good deal however these rifles are nothing more than a cheap plastic body around their cheap $125 standard .22 rifles. Very cheap, lightweight plastic parts, not like most polymer materials used by reputable manufacturers. For around $100 more you can build a better, aluminum upper
22 caliber AR rifle or pistol.
Other than that, the seller is good. I've bought many of guns, ammonium and accessories thru them successfully.

KGM R556 Heavy Use 5.56mm Suppressor Black - $399

And I thought that I wrote stories for a comment..lol. Jesus Christ man... while information is always good, writing something like this, especially something so hard to understand and follow is overboard...your points get lost in all the extra drivle.
