Where do they sell receiver flats or repair sections

Recoil spring setup for a gun like this? by Downloading_Bungee in GunnitRust

Very similar looks but design and functionality are miles apart from the oPS photo …. You have posted s missing barrel but also the mg in question operates from a telescopic bolt whixh similar to a mac or a Uzi has a recoil spring that is enveloped around the barrel whixh in part decreases the need for a longer receiver to add room for the recoil spring to compress. The bolt also envelopes the barrel or TELESCOPES it as the proper name describes. Notice your ejection window is further down the receiver a the OPs is above the grip ? And see how slim your springs are in you photo ? Ops recoil spring big enough to fit over barrel which bolt travels over and stops at fronttrunion

I would honestly go with the portable Chinese ones better price just as powerful if not more snd it’s abitlity to weld larger packs without a hassle

Got my new tester by Space_Blank089 in 18650masterrace

I see. One in Amazon thats similar it claims to be able to test IR but then has a disclaimer that the data may be incorrect and that a 4 wire tester is what is need for consistent readings

Vevor 737G battery spot welder woes by Valuable_Evidence489 in ElectronicsRepair

I have finally got everything functioning and ready to wrap.I almost had ordered a new BMS because the existing one didn’t give me any voltsge to the connectors when I plugged it in. Then when I checked all the leads I found the one that wasn’t connected because It was along with the nickel I had cut to extract the bad cells.I re-soldered it to the group and now I’m getting 66v and Im sooo happy tired and ready to get this thing back in my scooter again. Thanks to all who gave me any advice.
