Remington 770 .30-06 caliber air rifle: Remington has completely updated the 710 rifle, presenting the new .770-30 caliber 06. The updates and changes have mainly affected the action of the shutter, which has been made even more efficient.
Remington's new model 770 manual repeater rifle, heir to the 710 model, retains very little of the characteristics of its predecessor. The updates have in fact concerned the action system, the stock made more ergonomic, the strengthened magazine, a new aesthetic and more chambers available.
Starting from the action system, the latter is not very busy when firing, since the bolt closes directly in the extension of the barrel. Unlike the 710 model, the Remington 770 features a polymer and Teflon sleeve that guides the shutter only for the first 27,5 mm instead of the 129 mm of the 710, with the consequence that the remainder of the action is shaped with the shape of the bolt head. A further modification of the action concerns the length of the latter, since it has gone from the previous 153 mm to the current 174 mm, with a consequent lengthening of the ejection window by one millimeter. The polymer sleeve in the 770 is not fixed, but is removable since it is held by the retaining plate of the shutter release lever. The 41mm long integral tang holds the two-lever type trigger package in place.
The shutter has three locking lugs equidistant from each other, each about 10 mm wide and about 8 mm thick. The recessed extractor is attached to the inside of the bolt face, while the spring loaded pin ejector is placed on the bolt face. The substantial difference compared to the 710 model consists in the processing of the closing surfaces, which have undergone a change of angle in order to facilitate the opening of the shutter during the extraction phase of the cartridge case, obtaining the advantage of a greater speed of rearming. . The head is attached to the bolt body through a large pin with a hole in the center, to allow movement of the firing pin, while the cocking lever is flush with the bolt body. The bolt is not equipped with gas safety vents, the latter also absent in the extension of the barrel.
The feeding takes place through an 88 mm long single-presentation two-wire magazine, with the body in pressed sheet metal and provided with reinforcement ribs. Both the lower hoof and the elevator are black plastic, with a capacity of 4 shots which is reduced to three for the magnum calibers. The magazine is hooked directly into the stock, by means of a rocker lever located in the front part of the magazine housing, which has been profoundly improved compared to the 710 model in order to guarantee an even safer anchoring.
In the Remingotn 770 the classic metal sights are not present, but threaded holes are available on the back of the action to install aiming optics. As standard, the weapon is offered with a complete kit of Weaver-type sled and Bushnell variable 3- 9 × 40, ideal for hunting. The spotting scope benefits from a multi-purpose Duplex reticle capable of adapting to different situations in the hunting field: 330 mm long, with a weight of 425 grams, it has a pupillary output of 4,4 mm with a focusing distance of 89. mm and uses adjustment drums with stops every quarter of a moa. The weapon with the optics engaged has a total weight of 3.850 grams.
The barrel of the 770 model, instead of being hammered as in many Remington models, has undergone the buttoning process, which guarantees greater theoretical precision. It is no coincidence that starting from the 710 model all Remington rifled barrel rifles with closure in the extension of the barrel use buttoned barrels: the reason is above all of a practical nature, since working in a rotary hammer a barrel provided with closure in the extension of the barrel, either the roto-hammering process is carried out with extreme care, or the area intended for the seat of the closing tenons is also affected by the treatment, with the consequence that there is a risk of deforming the latter. The rifling is a six-start right-handed pattern with a pitch of 1:10 "(250 mm), typical of the Remington house. The extension of the barrel, as opposed to being screwed to the action or held to the latter by a series of pins, has been inserted by pressure: this has made it possible that, once mounted, the barrel can no longer be removed. The muzzle, with a diameter of 17,5 mm, has a crown recess type edge.
Another element that differentiates the 770 from the 710 is the stock, which has been totally redesigned in order to make it more ergonomic: made of glass fiber reinforced polymers, it has been corrugated at the grip points for a more effective grip. The latter is pistol-shaped and has an orange peel front and side, with a thin strip towards the front of the weapon, which gives it a more streamlined line. The fore-end has in the lower part a series of waves that continue on the side parts resume the anti-slip motif, participating in a better grip by the shooter and softening the line of the weapon, which is less rigid.
The guard has the Remington "R" imprinted, while the stock blade has a very pronounced Montecarlo cheek piece, in order to offer a better support to the shooter's cheek by facilitating the alignment of the pupil with the telescope. The trigger bridge, integral with the stock, instead of being a simple bow, has a visible thickening of the thickness towards the rear, to resume the motifs of the stock. At the rear, the black rubber pad significantly reduces the effect of recoil.
The quick release type t-shirt attachments were also created in the stock mold, which can also be used for mounting a bipod. In the internal part of the stock, in front of the magazine filler, there is the recoil lug which, when the gun is mounted, matches a notch obtained in the lower part of the barrel. The stock is connected to the gun by three screws: one that goes beyond the shank of the action, one in the front part of the action and the third that fits on the extension of the barrel, near the recoil lug.
The evolution of the Remington 710 rifle is called Remington 770 caliber .30-06, a weapon that has undergone profound modifications and updates that make it even more reliable and precise in the hunting field.
