Info on installing theSilent Thunder Ordnance" mag well in a 455/457 KRG Bravo

[jrhtx]

Tried this in the CZ457 post but no info.

Does anyone have better details on how to install a "Silent Thunder Ordnance" mag well in a 455/457 KRG Bravo?
No instructions came with the mag well, no return email from the company. Web site just says:
"Installation is as simple as inserting the rear "hook" area under the front end of the trigger guard and then rotating the front of the magazine well downward. This is typically a snug friction fit, so while on our sample no adjustment was necessary, in some cases minor fitment +/- may be necessary."

The part is so wide, more then 1/8" either side, at the hooks, no way it fits under the trigger guard. What am I missing?
Thanks

I just installed this mag well yesterday. The instructions suck. You don't put the part "UNDER" the trigger guard. With the rifle upside down install the wide portion of the well "FORWARD" of the trigger guard into the chassis opening. Then push the front of the well forward and down. I had to use a light soft face hammer to firmly seat the part. Tap the part down and forward.
