Dear sniper,
This is quite informative....and very useful for those who want to import/ buy any spring for ARs.
Only thing is this , at places no.of coils missing.

33 Coils gives the best performance...
My Samurai-3G in .22 cal is fitted with OX Accelerator Spring with 33 coils....
Its more than a year & over 1500 shots...consistently accurate till date
Briha

I understand that IHP National 25 resembles with Diana 25.
The dimension spring of my National 25.....ID 12.9 mm , OD 18.5 mm , 31 coils and wire dia 2.8 mm.

Accuracy is good but temparamental.

Velocity----535-550 Fps with MSFH 7.6 grns.
500-515 Fps with GSFH 8.2 grns.
