That I am not denying. So did most others. Where I grew up M1s were rare, so not that big of a sample size (6-8 maybe). I witnessed one broken shock bolt on the link (6 mm was not a good idea). But everything was cracking at the time, Giants, GT, Speci Big Hit. Exception was Nicolai.Karpiels, specializedeses, and yes turners
Stop dancing around. M1s broke. Frequently.
