500 rounds of 124 nato without any FTE using the end cap. I add the Choate (hk) and it immediately became unusable with the # of FTE’s. I read a recent forum elsewhere saying that they had dremeled away material on the end cap to match the same cutout as the stock end cap, allowing their recoil spring to have a designated slot and allow for further travel. Has anyone else modified their Choate in a similar way? (Stock locking piece, all MKE internals, MKE/mora mags)

I’ve got a 100 degree locking piece otw prior to this issue and I’d like to avoid replacing all internals to HK if I can.
