Has B5 gotten their stock fitment issues straightened out yet? I bought one from AIM Surplus last year that was so tight I couldn't move it once it was installed. I really like the profile of the SOPMOD stock but don't want to waste my time or money ordering one and having to return it if it doesn't fit right.
Thanks |

I really like the profile of the SOPMOD stock but don't want to waste my time or money ordering one and having to return it if it doesn't fit right. Thanks The "fitment" issues were a result of being provided incorrect drawings by the military, resulting in an entire run of stocks with an incorrect receiver extension dimension. B5 manufactured the stocks in accordance with the drawings and dimensions they were given. This whole run was DRMOed and sold as scrap, however, many dealers purchased them and began selling them to consumers without informing them that they were scrap. Some were able to use them, others had to modify, some simply could not and re-sold them at a loss. B5 Systems never authorized the release of the scrapped stocks on to the commercial market - and has never marketed a SOPMOD stock to the commercial market without the QD swivel, while all the DRMOed stocks were non-QD military versions. In general, as long as the stock has a QD, it's good to go. One without is most likely one of the scrap pieces. While it is possible that a few "good" military versions stocks "snuck out" and are available, their numbers are extremely small, and overshadowed by the vast number of DRMO stocks available on the market. ~Augee |

Where as my two newer B5 both have the built in QD. Are you only talking about the newer B5 stocks when you say they were never released without the QDs? |
| I was aware of the out-of-spec stocks that hit the secondary market. However I figured ordering from AIM Surplus would guarantee me a non-screwed up stock. I tried it on several different tubes and couldn't get it to budge once in place. Might give the B5 another go if I can find one instock from a reputable dealer. |
| I have a b5 stock (newer one) that was very very tight on the extension. It loosened up a little with use but its still very tight. I then bought a new extension from damage industries and it fits pretty much perfect now. Easy to move but almost zero wiggle at the same time. I mention this bc it seems like the b5s are picky when it comes to extensions. I can't say for certain if you bought a damage industries tube it would fix the problem but for $20 something dollars, it's worth a try. |

I can't say for certain if you bought a damage industries tube it would fix the problem but for $20 something dollars, it's worth a try. A certain amount of tolerance stacking will always happen with stocks, it's unavoidable when you think of how many different manufacturers are making stocks and "milspec dimension" receiver extensions - however, these reports tend to get lumped in with the reports of the DRMO stocks, and to some end up appearing like a more drastic and endemic problem. Part of the reason is the civilian market's insistence on "tight fitting" stocks which sounds all good and well until you get off the range and in to the field, and that tight stock becomes a bitch to do anything with as soon as a couple of grains of grit get in there - plus a nice "sandpaper" scraping sound when you actually do get the stock to move. Granted - I'm not looking for a rattle-trap, but I like my stocks a little looser on the tube than is apparently "cool" to have. I have fixed stocks, an ACS, and a CTR for when I want/need solid lockup - but I still prefer my slightly looser SOPMODs. IMHO - the MagPul fricition lock is a much better way to remove movment if it bothers you than overly tight stocks. But that's only tangentially related to the topic at hand.
