As angry as I got over the fit and finish on my ready to shoot weapon, these are set up in jigs and cut out like biscuits it will most likely fit.
Try loosening the breech "tang" I suspect its like mine the tang was inletted too low in front or at a downward angle in other words, they grind this pieces flat with the barrel before finishing so they will look normal when assembled, even though the geometery is off.
This may allow the hooked breech to slide back far enough to let the bolster to slide back far enough to clear the lock. It doesnt take much.
What to expect next? Your barrel wedges wont fit without some modification, Theres probably some cheap oil finish in your lock mechanism, fly and tumbler area especially a pain to clean out. My coil spring was all gunked up. And your rear sight if its anything like mine will be crooked or only partially adjustable and then wont stay adjusted. The consensus here is remove sight with a drift from left to right. If youre a right handed thrower place in right hand and throw in nearest trash receptacle. Left handers should follow a similar discarding procedure.
I on the other hand being such an ace craftsmanlike person :v used a hammer, a pin punch, a center punch, a couple of small files, a stronger spring and salvaged my rear sight to where it now holds a zero, had to file an 8th or so off the front, bottom line $600 rifle inc tax and shipping, about 12-15 hours of labor at ($5.20 an hour or whatever youre worth I charge $6.00 when I hire out!) a can of Minwax stain and Minwax tung oil finish $20, sandpaper 100-320 grit $7 bottle of cold blue $4 ...
... and now its almost usable :thumbsup:
After the first 70 or so rounds its tightening up about 2" group @ 50yds w/100gr 2F, the bore is smoothing out been polishing it with JB bore stuff looks real similar to baby excreta and costs about $9 for a small jar. Oh be sure to clean the protective grease out of the bore before firing, it requires some pretty aggressive cleaning denatured alcohol, paint reducer, carburetor cleaner etc, followed by something to like smokeless bore solvent followed by a few dozen dry patches, I dont know what the Hell they used but I only swabbed mine out before firing it looked clean but the resulting residue is like melted plastic hard fouling.
As for the customer service department, 3 emails unanswered I did follow up with a phone call, got transfered to "the guy" that allegedly knows stuff, sat on hold, never got voicemail or a connection to the guy, gave up.
They did accept my order for parts online, tap my card and deliver the goods (took 2 weeks).
