Hey guys, I'm haveing a problem with my SEAK and I'm hoping you guys can tell me what's going on. I can run about 1 mag through it fine. After that it's doing two things: The first thing that happens it that it fails to extract and then shoves the next round into the empty in the chamber. I have to then either tap out the empty with a rod or pry it out with a pair of needle nose pliers. this is happening every 10 to 12 rounds now. I've used both Silver Bear and Wolf and it happens with both of them. The other thing that's happening is that sometimes the next round attempting to be chambered after a shot gets only partially stripped out of the mag and the bolt then gets jammed between the bullet and the chamber ramp. I've got 7 magazines (the original 1 + 4 purchased with the SEAK and two orange ones) and it appears to be happening with all of them though I can't really be sure since the first problem interferes with testing of the mags. Any ideas as to what's going on? TIA Jeff |

Okay, first problem might be a weak extractor (if I understand you correctly, it's not holding onto the casing for extraction). The second problem, may be too much space between the mag catch and the receiver (IE: too thick of a selector stop plate). Does the back of your mags have up-down play when inserted? (I had the exact same problem on my screw build, and milling down the stop plate fixed it 110%). ETA: On second thought, with both of these problems, it may just be a bolt which slipped past QC. In any case, ORF were great with the previous guys' problems, and I'd give them a call on monday. |
I don't think the extractor itself is weak. It's stripping the rim off of the case (where it engages, it's not tearing the case head off!) and the case is stuck in there pretty good. I have to pry on it pretty good to get the fired case out and then it seems to "let go" or pop out all at once. As far as the mag play goes, I haven't noticed any, but I'll insert a mag later and try it out. Mine was one of the ones that had the wrong extractor that was recalled and sent back to ORF. I dunno, I'm kinda puzzled by this. thanks for the reply BTW. Jeff |

hhmmm... That's definitely something new to me, but it makes sense now. well, part of it anyways. It could be the chamber itself, if it was done with a well worn reamer. The taper at the end of the chamber could be to blame. If the end of the chamber isn't large enough, rounds at the larger end of factory tolerance will get stuck. Try chambering a .223 shell casing and you'll see. It ends up being *stuck* (same with 5.45 in .223 chamber). Same principal that's behind the tapered shanks of drill-press and lathes' drill chucks, which are held in place by nothing more than tapered shank and a fast insertion. If what I've said above is correct, the rifle needs to either be rebarreled, or the barrel pressed out and re-chambered. Either way, its more trouble than it's worth for you to worry about this. As I said before, You definitely should call ORF about |

the failure to extract could be 3 things: 1. weak extractor spring/improperly machine extractor claw. i highly doubt this is the cause of the problem. 2. a rough chamber finish or negative area is trapping the spent case. aain, i doubt this is the problem. 3. long headspace. return the rifle to orf and allow them to verify this and the above two conditions. orf stands behind their work and will resolve this problem promptly. they are good folks and want only 100% satisfied customers. the late (timing-wise), dufficult extraction is affecting the bolt speed and causing your feeding problem. call todd and explain the issue to him. i'm confident he'll take good care of you. |

Jeff, Have you tried cleaning the chamber? Sometimes there can be some sand that was stuck some where after sand balsting. It will break loose and wind up in the chamber. I have saw this a couple times and the weapon will act as you describe. Run a bore snake or brush through it a couple times and see if anything comes out. Please feel free email me directly with any questions. Mike |
Hi Mike, I sent you and Todd an email. Problem seems to persist even after cleaning the chamber. Jeff |
Right you are! Just read your email, Jeff. By all means, send it back. I'll figure it out and fix it ASAP! Rapid Fire Attn: Mike 537 N. Elm St. Troy, OH 45373 Mike |
