Akila Picatinny Rail Alu 20moa

High quality lightweight Aluminium Picatinny rail for our Akila Bear8H and Bear93H barrel extensions.

20moa

• Cost effective inclined mounting option suitable for longrange and precision rifle builds.
• Comes with Torx screws and hardened stainless steel locating & recoil pin.
  
• Available in Aluminium 20moa and Steel 20 and 30moa inclination/elevation.
• Finger friendly bevelled edges.
• The Locating/recoil pin ensures perfect alignment by working with the v block shaped interface of the rail on the curved surface of the barrel extension.

Specs

• Precise NATO Standard Rail Interface dimensions.
• 14mm height: measured at front, male slot height above curve of barrel extension.
• 6 female slots and 6 male slots rear of the barrel extension makes for 63mm rearward protrusion.
• Good clearance underneath for bolt housing travel.
• 7057 Aluminium, anodised to black matte finish.
• 90gram

Fitting

• We recommend Loctite 468 is used on the Torx screw threads. This will need heat if removed later.
• The Torx head screws should be torqued to 4Nm.
• The included locating pin has a excellent transitional fit in both the rail and barrel extension, it may need a light tap with a soft face hammer to seat home.
• For extra security, one can consider bonding the surfaces with epoxy; this maybe a factor for precision shooters desiring absolute peace of mind. This will make future disassembly difficult without chemical solvents. 

How to determine how much inclination you should build into your scope mounting solution I hear you ask?

1. Look up your scope specification and find it's maximum elevation travel. 
2. Divide this amount by 2.
3. Convert moa to mil or vice versa as required to compare with your scope mounts.
4. This number is the maximum amount of inclination/elevation you can have in your scope mount solution and still get the cross hairs back to parallel with the bore for a close range zero.

• You might choose some amount of inclination in the picatinny rail combined with some amount of inclination in the scope mount to arrive at your total inclination.
• Most supersonic calibres need about 3 to 4moa inclination to zero at 100 metres.
• This guidance assumes everything is straight and true on your rifle, scope and mounting system...

Example:

1. My scope has 30milrad maximum elevation travel.
2. 30 / 2 = 15mil
3. 15mil is the maximum inclination we can have in our scope mount and still dial the cross hairs back to parallel with the bore.
4. My pic rail and scope mount are marked in moa, so I convert milrad to moa:
5. 15mil x 3.4(moa per mil) = 51moa
6. My Akila pic rail has 30moa.
7. I use a Tier One Scope mount with 20moa inclination.
8. 30moa pic rail + 20moa scope mount = 50moa total inclination/elevation in my scope mounting system.
9. That's ideal; my scope will be able to zero at hundred metres and still be roughly 5moa off the bottom stop (4moa up needed for zero + 1moa excess available(51-50) = 5moa).

• I can estimate how much elevation travel I will have also: 50moa scope mount - 4moa zero elevation = 46moa. 46moa available up from zero to halfway + the 51moa available from halfway up to max elevation = 97moa. 97 / 3.4(moa per mil) = 28.5mil
• I use my ballistics solver to see that I have enough Scope dial elevation available to get my 7mm Blaser Mag shooting Berger 195gr EOLs from a 100m zero all the way out to 1850m. Beyond that distance I have to hold over.
• I could use more inclination in my scope mount solution, like a 30moa scope mount; I would get more range from the elevation turret but my zero at 100m would be above the point of aim (by about 6 inches in this case).
