CN5F (Castle Nut, A5, Forward Controls) is an extended version of CNF Forward Controls Design (FCD) have been making since 2018. CN5F is designed specifically for the superb Vltor A5 system, CN5F is 0.1" longer, and is as long as FCD can make a castle nut while ensuring backward compatibility, and the stock's ability to fully collapse on Vltor's RE-A5 and FCD's RE5F. Note: not all stocks will fully collapse on A5 compatible REs. For more information on the differences between RE-A5, RE5F and RE10/A5SR, please follow this link: https://www.forwardcontrolsdesign.com/Vltor-RE-A5-vs-RE10-A5SR_ep_78-1.html CN5F aims to cover as much of the threaded area of a receiver extension (RE) as possible. It could be made longer, but it will run into backward compatibility issues with some REs' timing when installing the castle nut and end plate on the RE. CN5F is made specifically for the Vltor A5 system, and it will allow even the longest carbine stocks to fully collapse on RE-A5 and FCD's RE5F. While CN5F will also work on standard TDP spec length RE, the additional length of the castle nut will prevent the carbine stock to fully collapse. Other than its length, CN5F shares common features with its smaller brother, CNF. The TDP spec castle nut is a simple and robust fastener that is almost perfect for the job it's tasked to perform. Over the years, FCD have consistently come up with two minor gripes, first is its staking notches seem rather shallow and short, second is FCD don't enjoy using the castle nut's wrench notches as serrations (FCD's fingers invariably find their way to these sharp cutouts) to rotate it towards to the end plate while installing it. CN5F (Castle Nut, Forward Controls) is based on the TDP spec castle nut, with couple of changes: 0.1" longer. Staking notches angle changed from 45 to 30 degrees, this results in longer (25% longer than TDP spec) and deeper notches than found on TDP castle nuts. Number of staking notches increased from 3 to 4, spaced equally on the CNF. The castle nut is to be staked in two places, FCD are not advocating staking in more than two places, CNF's 4 staking notches mean that, at all times, 3 will be visible and available for staking, it simply gives the user more staking location options. Coarse serrations on the wrench side of the nut, a single use feature to make it easier while rotating the CNF towards the end plate. It is FCD’s opinion that a castle nut should be staked per TM, CNF's and CN5F's longer and deeper notch reinforces the belief, that once installed and staked, it will not loosen without the user's deliberate action. Forward Controls Design like the idea of quick detach, but some things on an AR are meant to stay put, and considerable effort was made to ensure that by the original designers. CNF and CN5F are a continuation and evolution in that direction. CN5F is billet machined in 4140 PH steel, and black nitrided (Cerakoted FDE, OD green, and burnt bronze also available). As with everything Forward Controls Design produces, it is proudly made in the USA. Weight: 0.51oz Material: 4140 PH Made in USA
Uuden sukupolven A5 CASTLE NUT, nyt saatavilla!
A5 CASTLE NUT, OLIVE DRAB GREEN on Forward Controls Designin (FCD) kehittämä huipputuote, joka on suunniteltu erityisesti Vltor A5 -järjestelmää varten. Tämä tuote, CN5F, on pidempi versio CNF:stä, ja se on valmistettu vuodesta 2018 lähtien.
Tuotteen ominaisuudet:
- Pituus: CN5F on 0.1 tuumaa pidempi kuin edeltäjänsä, mikä mahdollistaa täydellisen yhteensopivuuden Vltorin RE-A5- ja FCD:n RE5F -malleihin.
- Yhteensopivuus: Vaikka CN5F toimii myös standardin TDP-spesifikaation mukaisilla RE:illä, sen lisäpituus voi estää karbiinimallin tukin täydellisen taittumisen.
- Staking notches: Staking notches -urien kulma on muutettu 45 asteesta 30 asteeseen, mikä tekee niistä 25 % pidempiä ja syvempiä kuin TDP:n versiossa.
- Urien määrä: Urien määrä on kasvatettu kolmesta neljään, jolloin 3 on aina näkyvissä ja käytettävissä stakattavaksi.
- Materiaalit: CN5F on valmistettu 4140 PH teräksestä ja mustaksi nitraatattu. Saatavilla myös Cerakoted FDE, OD green ja burnt bronze -värivaihtoehtoja.
FCD:n mielestä castle nut -tuotteet tulisi stakata TM:n mukaisesti. CNF:n ja CN5F:n pidemmät ja syvemmät urat tukevat tätä käsitystä: kun tuote on asennettu ja stakattu, se ei löysty ilman käyttäjän tahallista toimintaa.
CN5F on valmistettu Yhdysvalloissa ylpeydellä, ja se painaa vain 0.51 oz.
