I've had David Gentry or actually Dennis put muzzle brakes
on my Sako SS 75 .300 Win Mag. and my Win. 70 SS in .300 Rum.
They take the bite out of the 300 Rum and the Sako shoots like a .308.
Usually less than 2 week turn-a-round, depends on how you ship. For the extra 8 or 10 bucks have it returned 2od day.
Workmanship is faultless.
Dennis is going to re-barrel my model 70 when the season is over.
Nice people to deal with. When he said less than 2 weeks he delivered. Go with him, he's ok in my book.
