Extra crispy

by -

Added this main spring not too long after installing the ALG ultimate defense trigger with lightning bow. It added a crispness to the trigger pull that is hard to explain but is %100 noticeable.

High strength

by -

Quality product, it has a high tension strength as advertised. It gives the trigger a crisper break than stock springs. Also, depending on the brand/type of AK it may cause the charging to stick a bit. It's a little sticky on zpap, ok on vepr.

Quality must have

by -

Very good tight spring. Must have for an a
<br>AK either as backup or a replacement. Watch for the "bite" though. Install with a rubberband or zip tie as this spring does not hold together like the typical AK trigger spring. Zero FTF with this. Solid hits. Strong lockup

Broke when arrived

by -

The spring showed up in a bubble mailer in 2 pieces.

Works great with Alg AKT


This spring really compliments my Alg AK trigger with more noticeable spring tension resulting a firm positive take up and reset.
