4x32
x86-64 (also known as x64, x86_64, AMD64, and Intel 64) is a 64-bit version of the x86 instruction set, first released in 1999. It introduced two new modes of operation, 64-bit mode and compatibility mode, along with a new 4-level paging mode.
With 64-bit mode and the new paging mode, it supports vastly larger amounts of virtual memory and physical memory than was possible on its 32-bit predecessors, allowing programs to store larger amounts of data in memory. x86-64 also expands general-purpose registers to 64-bit, and expands the number of them from 8 (some of which had limited or fixed functionality, e.g. for stack management) to 16 (fully general), and provides numerous other enhancements. Floating point operations are supported via mandatory SSE2-like instructions, and x87/MMX style registers are generally not used (but still available even in 64-bit mode); instead, a set of 16 vector registers, 128 bits each, is used. (Each register can store one or two double-precision numbers or one to four single-precision numbers, or various integer formats.) In 64-bit mode, instructions are modified to support 64-bit operands and 64-bit addressing mode.
The compatibility mode defined in the architecture allows 16- and 32-bit user applications to run unmodified, coexisting with 64-bit applications if the 64-bit operating system supports them. As the full x86 16-bit and 32-bit instruction sets remain implemented in hardware without any intervening emulation, these older executables can run with little or no performance penalty,
while newer or modified applications can take advantage of new features of the processor design to achieve performance improvements. Also, a processor supporting x86-64 still powers on in real mode for full backward compatibility with the 8086, as x86 processors supporting protected mode have done since the 80286.
The original specification, created by AMD and released in 2000, has been implemented by AMD, Intel, and VIA. The AMD K8 microarchitecture, in the Opteron and Athlon 64 processors, was the first to implement it. This was the first significant addition to the x86 architecture designed by a company other than Intel. Intel was forced to follow suit and introduced a modified NetBurst family which was software-compatible with AMD's specification. VIA Technologies introduced x86-64 in their VIA Isaiah architecture, with the VIA Nano.
The x86-64 architecture is distinct from the Intel Itanium architecture (formerly IA-64). The architectures are not compatible on the native instruction set level, and operating systems and applications compiled for one cannot be run on the other.
Trijicon ACOG TA31-D-100310 CK FDE. This model has tritium, fiber optic, and can mount a RMR type optic above the ocular lens (no hardware included). Not using it on anything, some dust and rubbing from living in the safe. A few spots on the inside of the objective lens that are not visible when...
I’m selling my OD green Trijicon ACOG. This optic has only been mounted to one rifle and has less than 50 rounds on it — excellent condition. I’m the original owner and I’ve had it for less than a year.

Hey guys I have a Trijicon ACOG TA31RCOM4 4x32 for sale. It is brand new never mounted on a rifle. Bought last year from a distributor. So plenty of life left.
Asking $950 for it firm
Thanks!
Selling my trusty BSA .22 Special 4x32 scope. It includes aluminum unbranded rings. Many gophers have been slain using this scope and I've had it for many years, but now it collects dust. Perfect for a beater 10/22.
Trijicon ACOG TA-31F-G (Green Reticle) .223 BDC w/ American Defense QD Mount.
Gently used but never abused. The tritium is probably 2/3 strength in pitch black conditions. Fiber optics works perfectly even low light. Beautiful clear glass with a wide field of view. Includes Killflash and...
This is a nearly new Trijicon ACOG 4x32 TA01-B. It has a 7.62x51/.308 BDC reticle and is tritium illuminated, no fiber optic, that means that it is only illuminated at night.
It is mounted on a Larue Tactical QD mount.
I purchased it in september of 2019 and it has only been on my AR for a short...
Up for sale is an old Tasco Pronghorn 4x32 scope, with 2 sets of rings, the main tube is 1" and the rings are for both the .22LR dovetail and the standard Weaver/Picatinny rails. Has standard "German Modified Duplex" reticle. Asking $20 for the whole set.

Trades welcomed! Feel free to ask any questions
Can meet in the Vancouver/Portland/clackamas area
Looking to sell my scope it's a great scope just not my style! Retails for about 90$ I believe asking for 75$ obo!
Trades are welcomed preferably for a quad rail FF/drop in mid length or a BCG! Thanks for looking!
SOLD!!!
