Out of curiosity and low budget tska looking for tweaks for our beloved AK or any AEG. So made myself one just for testing purpose only. not sure though if i got the right shape but with masta rambo's pix mukhang pareho. tska P150 vs madbull 300 ( hop rubber + nob ) hmmmm hanap ako best cheap solution.
1st tried the madbull nob set the hop to the longest range without the BB flying up and got a good range and grouping for 60 to 70 human steps ang layo, BB flight was straight and grouping was almost as big as a 14inch mags/tire.. then i install my home made nob made of alambre ( sampayan ) hehehe set the hop tapos ayon naubos na BB ko hahahhaha.. bukas ulit at bibili ako ng BB. pero mukhang pareho din range sa madbull nob sa 1st 5 BB bago naubos hehehehe
balitaan ko kayo ulit.
btw after got the right hop setting binaklas ko gun to check the shape inside kung mag half moon shape and notice hindi naman nag half moon at flat straight shape lang pareho itsura ng stock, madbull and my home made nob.
ito pala gamit ko
