The Picatinny rail (/ˈpɪkətɪni/ or /ˌpɪkəˈtɪni/), or Pic rail for short, also known as a MIL-STD-1913 rail or STANAG 2324 rail (canceled), is a military standardrail interface system that provides a mounting platform for firearm accessories. It was originally used for mounting scopes atop the receivers of larger caliber rifles. Once established, its use expanded to also attaching other accessories, such as: iron sights, tactical lights, laser aiming modules, night vision devices, reflex sights, foregrips, bipods, slings and bayonets.

An updated version of the rail is adopted as an NATO standard as the STANAG 4694 NATO Accessory Rail.

Significance[edit]

Because of their many uses, Picatinny rails and accessories have replaced iron sights in the design of many firearms, and they are also on the undersides of semi-automatic pistol frames and grips.^[1] Their usefulness has led to them being used in paintball and airsoft.^[2]

History[edit]

The rail itself dates from work by the A.R.M.S. company in the early 1980s and Otto Repa in standardizing the Weaver design.^{[citation needed]} Specifications for the M16A2E4 rifle and the M4E1 carbine received type classification generic in December 1994.^{[citation needed]} These were the M16A2^[3] and the M4^[4] modified with new upper receivers where rails replaced hand guards.^{[verification needed]}

The rail is named after the Picatinny Arsenal in New Jersey, which was named 'after the Lenape-named peak overlooking the old forge, loosely translated to mean “rugged cliff by water” or “water by the hills.”'^[5] The arsenal was tasked in 1992 to develop a standardized mounting system after the U.S. Army was dissatisfied with the contemporary products on the market. The Picatinny team was headed by mechanical designer Gary Houtsma (who was awarded the Order of Saint Maurice Award in 2014 for this contribution^[6]), who took the measurements from 20 or so different Weaver rail products from weapons bunkers at Picatinny (and even sporting goods stores) and came up with an average set of numbers set on a 45-degree angled surface. Houtsma then took the specifications over to the production facility and requested they design a dimensioning style so the rail could be easily produced and inspected. The factory recognized the similarity of the purposed optics rail to the existing rail design on 105 mmhowitzers, so they chose to scale down the howitzer rail design and co-opted the production and inspection procedures. The team then sent the finished product over to Rock Island Arsenal for review and trial, and then to the technical data section to determine if it should be a standard or a specification. After it was determined that the new rail should be a standard, not a specification, it was adopted and fielded in 1995^[7] with the designation Mil-STD-1913, dated February 3, 1995.^[8]

A metric upgraded version of the Picatinny rail, the STANAG 4694NATO Accessory Rail, was designed in conjunction with weapon manufacturers like Aimpoint, Beretta, Colt, FN Herstal and Heckler & Koch, and was approved by the NATO Army Armaments Group (NAAG), Land Capability Group 1 Dismounted Soldier (LCG1-DS) on May 8, 2009.

Currently, many firearm manufactures include a Picatinny rail system , such as the Ruger Mini-14 Ranch Rifle^[9].

Design & specifications[edit]

The rail consists of a strip undercut to form a 'flattened T' or hexagonal cross-section provided with crosswise slots at intervals interspersed with flats that allow accessories to be slid into place from the end of the rail and then locked in place. It is similar in concept to the earlier commercial Weaver rail mount used to mount telescopic sights.

The Picatinny locking slot width is 0.206 in (5.23 mm). The spacing of slot centers is 0.394 in (10.01 mm) and the slot depth is 0.118 in (3.00 mm).^[8]

Comparison to Weaver rail[edit]

Whereas the earlier Weaver rail is modified from a low, wide dovetail rail, the Picatinny rail has a more pronounced angular section.^{[citation needed]} Designed to mount heavy sights of various kinds, a great variety of accessories and attachments are now available and the rails are no longer confined to the rear upper surface (receiver) of long arms but are either fitted to or machine milled into the upper, side or lower surfaces of all manner of weapons from crossbows to pistols and long arms up to and including anti-materiel rifles.^{[citation needed]}

The only significant difference between the Picatinny rail and the similar Weaver rail are the size and shapes of the slots, where the Picatinny rail has square-bottomed slots while Weaver rails have rounded slots.^{[citation needed]} This means that an accessory designed for a Weaver rail will fit onto a Picatinny rail whereas the opposite might not be possible (unless the slots in the Weaver rail are modified to have square bottoms.)^{[citation needed]}

Weaver rails have a slot width of 0.180 in (4.57 mm), but are not necessarily consistent in the spacing of slot centers.^[10] While some accessories are designed to fit on both Weaver and Picatinny rails, most Picatinny devices will not fit on Weaver rails. From May 2012, most mounting rails are cut to Picatinny standards.^{[citation needed]} Many accessories can be secured to a rail with a single spring-loaded retaining pin.

Description

The Kinect™ by KDG for M-LOK™ is a revolutionary QD mounting system that will change the way we attach accessories to our modular weapons platforms. Much like the Sidelok™ for Picatinny attachment, Kinect™ insures proper and easy installation, eliminating common variables that would cause issues.(ie: over tightening) Although revolutionary, Kinect™ is quite simple in its operation. There are two spring-loaded wedges in the base of the Kinect™ mounting point. When you press the accessory or rail section down in the M-LOK™ slot, two tiny deployment triggers get pressed against the rail firing the wedges into place. There is nothing more frustrating that fiddling with an allen wrench (if you can find it) to get your accessories on an off your weapon with traditional modular rail sections. This changes the whole dynamic of the M-LOK™ system and really makes every accessory truly removable with the ability to mount it in a second when needed.

How Long Is A 3 Slot Picatinny Rail

**NOT RECOMMENDED FOR USE AS A BIPOD ATTACHMENT POINT ON CALIBERS LARGER THAN 5.56 and certain bolt action firearms. Due to loading the Bipod, the QD Kinect system can disengage from recoil.***

***Please Note: The Kinect system was designed and manufactured to the original specifications set by Magpul Industries for a rail thickness of .080″ and .125″ thick. The current specifications for M-LOK are a thickness of .080 to .150″ as many of the polymer M-LOK products on the market have to be thicker to support glass filled polymer rail systems. Therefore we do not suggest, nor can guarantee our KINECT product will work on these polymer products. Polymer rails can be modified to work, but our Kinect system was intended for use on precision machined aluminum rails within the specification of .080″ to .125″ overall thickness. With the variable tolerences that polymer parts are capable of, it is not suggested you buy Kinect QD M-LOK mounts unless you are sure the rail is within the specification, or you are able to modify your rail to fit the Kinect system. Measure the thickness of your polymer rails before ordering. If you have purchased a Kinect piece and it will not work with the poylmer or other thicker after market M-LOK accessories, we do offer a 30 day return policy for store credit on purchases. We will make sure you get taken care of!

***The Kinect Pieces are made fully assembled from the factory and not intended to be disassembled by the end user. Because these are mechanical items, all kinect pieces are tested multiple times at the factory to insure they work properly and are securely mounted onto M-LOK rails. So if you see marks of use on your new Kinect piece, do not worry, that is the factory test marks. Since the M-LOK system has varying tolerances, each Kinect piece may attached differently to each different manufacturers rail. (ie: thicker rails, thinner rails, rails of different materials) Kinect was designed to work with the full range of M-LOK accessories on the market. If you have any issues with your Kinect piece, contact us right away so we can fix the issue for you! Info@kineticdg.com
