Could you post more pictures of the areas from your earlier description: "Anyhow the gun isn't perfect in cosmetic condition and I modified the magazine for optimal reliability which changed how it mates to the bolt catch so the bolt doesn't hold open after the last round is fired." And also, is the scope still under warranty from ATN? Thanks
Magazine modified - cut out the contact point for bolt catch and heat treated mag lips to better contain cartrIdges TO IMPROVE cycling. Basically when I recountoured the mag the bolt catch was effected and so I eliminated it from the magazine ONLY
The bolt catch is intact and untouched - as you can see you can manually set it to hold the bolt open.
Top rail is nearly pristine
Gun functions 100% , I disclose all the above to ensure there are zero surprises when I meet up with a buyer - your and my time are valuable so why not fully disclose !
If you desire the bolt hold open (on an empty mag) to work again all it takes is a new magazine - it recommend the newest design instead of the polymer based on the tweaks needed to function 100%.
