If you didn't do it, then someone did do it when you weren't looking... It was dry fired, and the hammer hit the bolt catch - and broke the pin/screw, whichever...
Cali_Ed Posted January 30, 2014 Author Report Posted January 30, 2014 I literally just installed it and it had tension when i first picked up the receiver so I'm like what happend i didnt bang the receiever or anything
98Z5V Posted January 30, 2014 Report Posted January 30, 2014 (edited) Your lower has the screw, right, and not a roll pin (in that area/part)? Sometimes, if you tighten that screw too much, it'll break at first use or first push. Some DPMS screws disintegrate upon installation... <dontknow> Edited January 30, 2014 by 98Z5V
Cali_Ed Posted January 30, 2014 Author Report Posted January 30, 2014 Yeah its a screw that came with the tm lower, the screw looks fine i took it off but can't get the pin out to investigate. I tested the bolt catch in a sense of pushing it and feeling the tension was there when i first installed it and it worked fine.
Toolndie7 Posted January 30, 2014 Report Posted January 30, 2014 If you try to hold the catch so its not touching the pin and hit the recv on a hard non marring surface you might get it out. Good luck.
survivalshop Posted January 30, 2014 Report Posted January 30, 2014 (edited) A good Magnet , invert the lower so the pin can drop out to the magnet( might take some finagling ) Unless the separate catch pin is jammed into the far end of the hole . Sounds like theres some thing not right with the Bolt catch spring . The spring & detent hold the catch in a rest position ( out of the way of the cycling BCG ) until the magazine follower push's it up on last round to hold the BCG locked back . Photo's would be nice . Edited January 30, 2014 by survivalshop
Cali_Ed Posted January 30, 2014 Author Report Posted January 30, 2014 I'll have to post some up on my lunch break. And see if i can find a magnet. Thanks
Cali_Ed Posted January 30, 2014 Author Report Posted January 30, 2014 (edited) Here a video i took of it http://s838.photobucket.com/user/EDUARDO88/media/Mobile%20Uploads/trim8C2B8825-B8BF-4250-8BB5-A7B29A3718F7_zps74f6a7d6.mp4.html Edited January 30, 2014 by Cali_Ed
98Z5V Posted January 30, 2014 Report Posted January 30, 2014 Zero spring power, returning it? Was that gravity dropping it back down?
Cali_Ed Posted January 30, 2014 Author Report Posted January 30, 2014 Yeah it's like all of a sudden the spring is gone and has no tension
98Z5V Posted January 30, 2014 Report Posted January 30, 2014 You didn't, by chance, use the disconnector spring in there by accident? They're very similar, but the disco spring has one flared coil at the end of it, to keep it wedged in the bottom of the trigger. A disco spring, inserted with that flared coil outboard, then the detent inserted into that flared coil - would wedge itself down in the hole... Thus, compressed, stuck spring in there providing no spring pressure.
Cali_Ed Posted January 30, 2014 Author Report Posted January 30, 2014 I'm not sure i orderd the spring specifically ill hAve to double chek once i get it te pin out some how to remove the bolt catch
98Z5V Posted January 30, 2014 Report Posted January 30, 2014 Check your trigger - if you have a straight spring in that trigger, for the disconnector, then the disco spring has gone somewhere...
Cali_Ed Posted January 30, 2014 Author Report Posted January 30, 2014 Ill hVe to check when I get home i have a ssa-e if that helps any
98Z5V Posted January 30, 2014 Report Posted January 30, 2014 Yep, disregard. G triggers have their own parts already... How'd you put this all together? Not a complete lower parts kit? Stripped down lower parts kit, minus trigger, then the G trigger? Or, all small parts for a LPK ordered separately. Even if you don't have a disco spring somewhere, you might have been sent one by accident, instead of the correct spring... Just thinking out loud here, trying to figure out what's going on. From what that vid shows, it's the only logical solution to what's going on here...
98Z5V Posted January 30, 2014 Report Posted January 30, 2014 These two guys in the red circle here - easy to confuse:
Cali_Ed Posted January 30, 2014 Author Report Posted January 30, 2014 It was. Parts kit i had laying around but had to order that spring cus its in my other lower. Ill hae to check when I get home you've been a great help thank you sir
98Z5V Posted January 30, 2014 Report Posted January 30, 2014 you've been a great help thank you sir Bah - just trying to "pay my rent." Drew charges me a fortune just to log on here, and the more I post, the more he lowers my rent... <lmao>
Cali_Ed Posted January 31, 2014 Author Report Posted January 31, 2014 Took me a while went a hung out at shooters whare house for a while lol
Cali_Ed Posted January 31, 2014 Author Report Posted January 31, 2014 (edited) Been banging away at my lower and the pin wont come out :( Update : So i pushed the bolt catch pin like if u was trying to engage it and held it in then banged it and now it works? I'm not sure if i should leave it alone or continue to bang at it to get the pin out and check the spring? Edited January 31, 2014 by Cali_Ed
survivalshop Posted January 31, 2014 Report Posted January 31, 2014 Could be a problem with the bore for the spring & buffer , burr from machining or just filings in there . Seems a few people are having problems with that pin on the TM. Lowers . I will Email them & ask what is up or you can go to there web sight , they have a Forum there, last time I looked.
survivalshop Posted January 31, 2014 Report Posted January 31, 2014 TM response If they tightened it like superman then the steel dowel will press fit into the softer aluminum and will require to be cut out. I would imagine you could tap the dowel but that is a tiny piece of metal to tap. As long as they did not press fit it in then yes what you mentioned the "tip & tap" method will work. You unscrew it. Then re-leave the spring tension with one hand and hit the buttstock or buffer tower (if no stock) on some wood or plastic and the dowel will start to come out via inertia. Then when you can see a touch of it out of the hole then use a pair of pliers to pull it the rest of the way out. We used a two piece design due to the DMPS threaded rod has a habit of breaking when you try to remove it and thought this method would be better. Nathan
Cali_Ed Posted January 31, 2014 Author Report Posted January 31, 2014 Thank you sir i must have super tightens it but i dont rememer it lol
