I just got a replacement LBRS from polymer80 as the original was so far out of spec there was no way to get the OEM Glock slide onto it. Slide would hit the rail and just stop. (See pic) The new LBRS not only fit but looked a lot better too.
Anyway, it felt great getting the slide on right up until I hit the rear rail section And came to an abrupt stop! I’m thinking WTF, what new hell is this?
First thing I do is take to the interwebs to see if MGB was a fix and sure enough he does and it looks like an easy one too.
Thanks MGB !
MGB... i sanded right through the center like you said not to... Acutally it didnt crack but its so thin i can see through the housing so i ordered two more so i have an extra. I will stay away from the middle next time
MDX sold out of the trigger housing. Link has been updated to in stock 20qty LWD 👊
I found MGB on Youtube. After watching more and more videos I could see the knowledge and pride on the builds. As a Retired USAF HD Vehicle Mechanic and a Union HD Truck Mechanic (28 yrs total) doing the job right the First Time is very important. I have a few P80 and a SS80 build that I have not started. I am confident with the resources of this group, the builds will go much smoother ! I joined this group to Educate myself, Share information with others and Support the MGB Site. Looking forward to meeting everyone.
