yep no problem at all
if you can tell me the distance from the front of the nea gas block to the back side crush washer.
we are thinking the first ones we will do will be like this and the spikes unit, which are about 5.5 inch long and 1.25 on the OD.
we can bore out more of less to get the right length.
I.E. if you wanted one on a 10.5 inch ar in 223 we would only got in a bit, if you were planning to cover most of a 14.5 drill a little deeper, or just thread it from the muzzle end.
Ive got a bunch of nea rails at the shop so ill see how much space is In the new ones.
