I ordered a +30 based on their recommendation, and it still has pin fall. I may order a -10 and try it. Did you have to file/machine a notch in the hanger for the roll pins in the trigger? Fitting the hanger with a Shilen trigger was a little more involved than plug n play on this one.
I had a bad experience with Mack Bros customer service as well. A friend of mine purchased an aftermarket replacement Rem 700 bolt from them and I installed and mated it to his receiver. The machining was very nice. I like the quality of the bolt but for some reason there was insufficient extractor tension. I sent an email asking for their suggestion and got . . . crickets. No reply at all. A certified gunsmith friend of mine looked it over and replaced the extractor spring. Problem solved. I was hesitant to tinker with the bolt thinking since it was brand new I didn't want to void any warranty by adjusting things myself. The situation turned out fine and everything is working as it should now, but the lack of response from Mack Bros was concerning to me. They may be very sharp at design and production but customer service is also super important. I hope this will be remedied. I really like giving my business to a couple of brothers in South Dakota! Made in the USA!!
