у них с дельтой давняя дружба и тесное сотрудничество, еще с момента образования девгру.

The barrel blanks have a 1:8 in (203 mm) twist and are stainless steel.[citation needed] They have a unique heavy barrel profile, starting with 0.980 in (25 mm) in diameter for the first 2.60 in (66 mm) of length, then narrowing down to 0.850 (22 mm) in diameter, 0.750 in (19 mm) in diameter underneath the front sight block, and 0.725 in (18 mm) in diameter to the muzzle.

Beyond this, exact specifications vary. Since they were built in house, they seem to have been accessorized to personal preferences, with fixed (A1 and A2 styles) and retractable butt-stocks. (Original 4-point and improved 6-point Colt stocks, and the Crane/SOCOM/LMT stock are all in use.) Recon rifles built by Crane are reportedly all fitted with a free-float handguard system, the most popular being the Knight's Armament Co. M4 Match RAS and the LaRue free-float handguards in the longer lengths (which protect the barrel and provide more area to mount tactical accessories).

I get more questions about the “Black Gun” with a suppressor than any other weapon that I post. I called this black beauty my Recce Rifle, which the unit armorers could take an ordinary M-4 with a 16″ barrel and make it shoot 1/2 MOA groups at 100m. As a sniper, I chose this gun from my gun lockup over the other dozen guns if I needed a light weight, precision instrument for a mission that I could also use as an Assault Rifle inside a structure if needed. The suppressor was made by Knight’s and never failed me, but as much fun as these suppressors are to shoot, the extra cleaning balances it out.

Larry Vickers offers these additional observations:

The early Recce rifle efforts started in the Delta Sniper Troops in the early 1990’s – post Operation Just Cause timeframe.

A variety of things were tried (such as stainless steel match barrels) but the improvements narrowed down to a few areas; improved ammo, improved triggers, a variety of optics and lastly free float hand guards and eventually rail systems. These efforts pre date the Mk12 in NSW use by many years.

Knights Armament played a big role with development of both enhanced triggers and free float rails coming out of this program. Reed Knight said from an early stage that better ammo would yield much better results than match barrels and he of course was correct. Delta pushed forward with acquiring better ammo that has led to much of the specialized 5.56mm ammo on the market today. Black Hills and Hornady both offer loadings as a direct result of these efforts.

The rifle shown in this picture had an early SR-25 carbon fiber free float tube adapted to it. This became a common modification in Delta to get more real estate for lights and lasers and better zero retention vs the carbine length KAC rail. This led to the development of the KAC MRE rail which was the first extended length rail of its kind.

Also the scope in this pic is a Microdot – a Japanese 1.25 x 4 off the shelf commercial grade scope that had a red dot in addition to a reticle. This was a stop gap optic after the need arose in Mogadishu Somalia for better target ID vs a red dot sight in the street fighting of that battle. Eventually Leupold offered an optic ( the CQT) at Deltas request to fill this need. It didn’t really answer the mail for Delta so I approached Schmidt & Bender on the Units behalf to build a more suitable optic. This is how the S&B Short Dot was born.

Delta played a critical early role in the SPR program ( later Mk12) that we know of today. In typical Unit fashion they did it quietly without books, movies and public spectacles of ‘who shot who’ played out for the world to see. The True Quiet Professionals.

Забыл закавычить.

То есть получается, что "Реки" это AR-образное под 5,56х45, заточенное под большую точность, а набор компонентов зависит от периода.

неа, я на полном серьезе.

Дельта вон судя по всему не заморачивалась высокоточными стволами

оффтоп: кажется на mod H ARMS swan sleeve снимался нафиг

Если Дельте надо было далеко стрелять, они брали СР-25. А так снайпер с карабином - обычное дело. Для полицейских операций м4 хватает, а если что, снайпер может и внутри адреса поработать с карабином.

Я знаю. И подозреваю, что именно поэтому дальше экспериментов он не пошел. Тем более с таким стволом он не такой уж и компактный.

по черным лифчикам - вот это что все-таки такое ? вроде и AWS, но не strike/SF/"ak".

Что терзаться? ANVIS-9. Шлемы на тот момент уже MICH 2000,черные или зеленые. Из фишек то, что АНВИС маунт присверливался прямо на шлем, безо всяких адаптеров.
