I have a feeling the threads are a little loose in fit. The yellow is tight, but it held together inserting it. The loose fit could be why blowback is so bad. I have another breech plug, but it's not a 7/16 hex to remove. It's the old one with two flats on a round end. As long as the teflon tape is working I'll just keep using it.

Very pleased with the groups I'm getting. Like I've said before, the fit & finish on this rifle is terrible but everyone should own at least one rifle they arent afraid to get wet & dirty. This may be the perfect one to use in bad weather. A little water & mud wouldn't hurt the looks a bit, and the way it shoots the deer would still be in serious trouble.
