IZH-61, MP-61 parts spare tuning Baikal upgrade made from only hard pieces, improved set transformation "Jax" kit number 1 (basic).

The proposed improved basic kit of tuning includes:

1. New full-bodied, functional front piece with a built-in picatinny rail, convenient side mounts and a rack (updated design with advanced features).

The proposed set is perfect for upgrading all versions(MP-61, IZH-61, MP-60, IZH-60), both early (iron) and late (plastic). These improved front piece are well and quickly installed in place of standard front piece. The new full-bodied includes:

- base with a picatinny rail that is integrated at the bottom front for reliable and convenient fastening of various additional accessories: bipod, tactical handles and other similar products,
- rack for connecting and firmly fixing the base, which has the shape of an eight with a specially enlarged central part of the cylindrical shape that is ideally suited for the installation of various devices: a cylinder, a range finder, a flashlight and other components for more comfortable and efficient use. At the top of the rack there is a built-in standard dovetail mount,
- four durable hardened mounting screws.

Benefits of an improved front piece:

- made of reinforced plastic with glass filler, that is, it is more durable and impact resistant,
- due to the high rack, the base is lower, therefore vibration is less felt, which makes use more pleasant and has a positive effect on stabilization,
- the new modernized base it is a monolithic one detail and there are no voids inside it, so it all consists entirely of a single durable plastic.
- on each side there are special places for mounting any other devices, 
- has a beautiful appearance and modern design, has aesthetic stiffening ribs on the sides, which look good and increase the strength characteristics, perfectly fitting the appearance of the product, while not increasing its weight, thanks to its well-thought-out construction.


2. Detail locking the rear part of the cylinder, also for lengthening and fixing the butt with two seats, made of strong plastic.

The proposed locking part is ideally suited for all MP-61 and MP-60 models. Reliable fastening of this part occurs due to the locking steel pin. This back also serves to lengthen and has two seats for a special washer for holding and adjusting the rolling butt stock. Made by means of a new mold of more durable plastic.

3. Ring blocking the lever is made of high-strength plastic, which makes it reliable,

4. Upper spring providing preload on the locking ring,

5. The bottom screw securing the locking ring,

6. Upper locking latch made of strong heat-treated steel,

7. The spring of the upper locking latch, made of durable high-quality wire,

8. A spring of replaceable rails made of durable high-quality wire,

9. Retainer spring rails,

10. Spring stop(pin) for rails,

11. Reliable sturdy steel pusher,

12. Pusher spring made of durable high-quality wire,

13. Steel rod locking back part,

14. Butt stock,

15. Screw with washer and nut for fixing the butt stock,

16. Pin for pusher,

17. Pin for latch,

18. Three wear-resistant polyurethane sealing elements,

19. Gas spring of reinforced construction. The main advantages:

- significant reduction in vibration,

- tactile sensations will change for the better: the cocking process will become smooth, the lever stroke will be soft, the recoil will decrease, due to which, with intensive use, the hand will be less tired and the load on the joints will decrease,

- absence of various unpleasant accompanying sounds that occur on products with a twisted spring,

- leave the product in the cocked state for a very long time and at the same time do not worry about the fact that after you have to change the spring,

- provides stable indicators with minimum deviations,

- accuracy will significantly improve,

- excellent power data.

20. Cylinder monolithic reinforced heat-treated steel strong construction improved tuning. The main advantages:

- has a specially increased weight + it was heat treated (hardened) and it has thicker walls, is made of solid full bar on a high-precision CNC machine, material steel 50 - this steel is much more wear-resistant, which positively affects the strength characteristics, durability and performance in general, especially This is important in places where the cylinder interacts with other parts.

- outer and inner surfaces of the new cylinder have a noticeably better roughness, unlike the old model cylinder, which consists of three parts and in the process of working, the connection tends to loose, and the pin in contact with the wiping surface of the pipe wears it out a lot, which results to the deterioration of compression and, as a consequence, the inevitable fall of the main indicators, which in turn contributes to significantly faster wear of the cylinder itself and parts in contact with it.

- durable coating of the new improved cylinder - chemical oxidation by oiling preserves surface roughness, both internal and external, which positively affects the reduction of spring friction on the cylinder and the cylinder itself on the pipe, thereby achieving stable performance.

- to use the gas spring in the new model monolithic cylinder there is a special recess (recess) under the gas spring rod. When using a gas spring, now there will be no defect (destruction of the connection by the pin of the cylinder fungus) - which is present on the products with the cylinders of the old sample and as a result leads to the breakage of the cylinder itself.

- new improved monolithic cylinder, in comparison with the non-composite(cast of 35 steel without heat treatment) cylinders of the old model, in addition to the weighty advantages indicated above, also has a more advanced design that allows you to achieve the maximum possible effect and in the aggregate get the best results.

21. convenient lever with a new faster and more reliable locking mechanism, made of sturdy steel with built-in steel connecting rod to interact with the pusher and mounted on it durable plastic handle which has by two fixing screws,

22. A full complete of the lower mechanism of pressing with all the necessary elements and springs,

23. Front housing insert and screw for her reliable fixing (not shown in the presented photo, but included in the shipping package),

24. This advanced basic kit "Jax" number 1 is ideally combined with additional kits "jax" numbered 2 and 3. You also can choose an additional multi-level configuration depending on your needs and preferences.

The package delivery includes hard improved tuning basic kit "Jax" for upgrade.
