Thread: Dodgy recoil lug

Yes, file it with a very slight forward taper and polish the surface with wet & dry backed by the file. Breaking the sharp edges also helps. Bed from the front edge of the mag well to about 50mm up the barrel, and from the rear of the bolt stop slot back. Take care to fill the holes and trigger slot with putty or plasticine. A plastic shim cut from a plastic ice cream lid and put under the mag well will give a nice clearance off the stock but still be close enough for all parts to line up nicely.
