Description
 
This kit allows you to replace the breech seal for your DIANA Action Line air rifle. Fits the following airguns:
DIANA Eleven
DIANA Twenty One
DIANA Two Forty
DIANA Two Fifty
DIANA Two Sixty

Worn breech seals can cause loss of muzzle velocity and inaccuracy.

These breech seal O rings have a lower durometer rating than the factory seal. This provides improved air tightness - eliminating lost air that reduces muzzle velocity and shot-to-shot inconsistency. These breech seals are also 3X more consistent in thickness than the factory part. This is a very important benefit!

Testing at Archer Airguns indicates that after correct installation of this kit, muzzle velocity increased by an average of 15 FPS. In addition the Standard Deviation (the statistical measure of shot-to-shot consistency) improved by an average of 40%.

The kit includes:
2 precision machined steel shims
4 high-quality, Buna rubber O ring breech seals (3 are spares)
Comprehensive illustrated instructions
