||Bought this M4 from Buds a while back and finally put her through the paces today.
I tried 4 different types of ammo and all but one worked 110%. I left the spring adjustment where it was set from the factory.
1. Federal bulk #750 36 gr. worked perfect(fired 200 rnds)
2. Winchester Wild Cat WB22lr 40 gr worked perfect(fired 200 rnds)
3. Winchester Supreme S22lrruhv 32gr(1640 fps) worked perfect (fired 100 rnds)
4. Federal Auto Match......she did not like this stuff one bit.
Outstanding gun with outstanding accuracy! I started with the Auto Match then went to the others with NO problems what so ever.
I have a BUIS and Primary Arms micro dot for sights(absolute co witness) and everything was about 1" low @ 50yds. Made the needed sight adjustments and she was just a solid as any could ask for.
I see a few more of these in my near future!
And a big thinks to Buds....you guys are great to deal with!!
