flash can
Flash memory is an electronic (solid-state) non-volatile computer memory storage medium that can be electrically erased and reprogrammed. The two main types of flash memory are named after the NAND and NOR logic gates. The individual flash memory cells, consisting of floating-gate MOSFETs (floating-gate metal–oxide–semiconductor field-effect transistors), exhibit internal characteristics similar to those of the corresponding gates.
Flash memory is a type of floating-gate memory that was invented at Toshiba in 1980, based on EEPROM (electrically erasable programmable read-only memory) technology. Toshiba commercially introduced flash memory to the market in 1987. While EPROMs had to be completely erased before being rewritten, NAND-type flash memory may be erased, written and read in blocks (or pages) which are generally much smaller than the entire device. NOR-type flash allows a single machine word (byte) to be written – to an erased location – or read independently. A flash memory device typically consists of one or more flash memory chips (each holding many flash memory cells) along with a separate flash memory controller chip.
The NAND type is found primarily in memory cards, USB flash drives, solid-state drives (those produced in 2009 or later), feature phones, smartphones and similar products, for general storage and transfer of data. NAND or NOR flash memory is also often used to store configuration data in numerous digital products, a task previously made possible by EEPROM or battery-powered static RAM. One key disadvantage of flash memory is that it can only endure a relatively small number of write cycles in a specific block.Example applications of flash memory include computers, PDAs, digital audio players, digital cameras, mobile phones, synthesizers, video games, scientific instrumentation, industrial robotics, and medical electronics. In addition to being non-volatile, flash memory offers fast read access times, although not as fast as static RAM or ROM. Its mechanical shock resistance helps explain its popularity over hard disks in portable devices.
Although flash memory is technically a type of EEPROM, the term "EEPROM" is generally used to refer specifically to non-flash EEPROM which is erasable in small blocks, typically bytes. Because erase cycles are slow, the large block sizes used in flash memory erasing give it a significant speed advantage over non-flash EEPROM when writing large amounts of data. As of 2019, flash memory costs much less than byte-programmable EEPROM and had become the dominant memory type wherever a system required a significant amount of non-volatile solid-state storage. EEPROMs, however, are still used on applications that only require small amounts of storage, like in serial presence detect.
Flash memory packages can use Die stacking with through-silicon vias and several dozen layers of 3D TLC NAND cells (per die) simultaneuosly to achieve capacities of up to 1 terabyte per package using 16 dies and an integrated flash controller as a separate die inside the package.
I have a PSA 6.5" upper receiver with the following info:
The Upper is used in good condition with about 500 rounds through it
Barrel: 6.5" 4150V Chrome Moly vanadium steel, nitride treated for durability, and chambered in 5.56 with a 1 in 7" twist. Finished off with a PSA 9" M-lok Rail, a low...
Looking to sell a PSA 7 inch 5.56 upper that is exactly as listed on their site. It's a shortie boi with only 3 mags through it, in good shape with very few tiny dings from sling wear. Bought it as a "for funsiez" build but I'm trying to consolidate to just one AR and 7inch isn't the "one AR to...
I have some extra parts for sale:

PSA 9mm buffer 5.5oz with 9mm Buffer spacer made from cut down buffer $10 SOLD
PSA Fatty mid length handguard with heatshield $10 SOLD
PSA 3 A2 grips sized slim, medium, and fat $10 for all 3
Magpul PRS extended...
KAK muzzle device/ flash "can" hider for 300 blk barrel thread pattern 5/8x24. These actually reduce felt recoil a good amount and almost totally eliminate flash. Like new, No marks, less than 50 rounds through it. $40 retail, I’m asking $20 plus shipping or local meetup in greater Spokane.
Used only twice, in very good condition, see pictures. This was part of an SBR build that I have recently reconfigured as a Commando.
$25 Cash, Paypal Friends and Family, VenMo, or CashApp.
Free ship in the Pacific Northwest by USPS First Class. In person only M-F 7am-2pm at my company in...
I bought it used for a project and then spent all the money for that project on other things :rolleyes:
It's been used but I have no idea on round count or why, barring any signs of abuse (of which there are none) why round count would really matter
Preference would be PP F&F but cash would be...
Brand new PSA 5.56 Fluted Flash Can. Installed on a barrel that has never been fired. I removed it because I decided to go a different way for this build. My loss is your gain! Save off the retail price plus the cost of shipping and taxes...
Switched to a strike cookie cutter so I no longer need this. Only has about 150rds through it. Works phenomenally. Will even help your 300blk cycle subs without a Suppressor. Purely moving away from this because I want my pistol as short as possible for my backpack. 5/8-24 threads...
Lightly used
Ballistic Advantage 9MM Modern Series 8.3 Lightweight Barrel (1/2-28) $100
KAK flash can $20
Trades considered please note when offering trades please note trade value of your items or at least say I will trade this for that. Some of the specific parts I am looking for are...
Two Kak Industry Flash Cans. They're basically blast diverters. I had them on an AR pistol for a couple hundred rounds. They're nice because they direct most of the blast downrange. And they look cool. They're ½ x 28 threads. The small one is the Micro model and the other is the Slim...
As new KAK extended length flash can. It's been installed but it shows no wear from use that I can see. 1/2x28. 5" long, 3/4" wrench flats. See Kak's website for complete specs and price. Lets try $34 shipped via USPS first class with tracking. First I'll take it followed by an convo gets...
For sale is a 8.5" 5.56 1/7 twist Nitrided complete upper with BCG and charging handle. less than 50 rounds down range, shoots perfectly. Included Midwest Industries flash can cuts down on concussion and kills the flash. Including a BCM KAG angled grip. AT3 Tactical Billet upper with 9" Mlok...
