125 gr NBTs; 16.5 gr WW296; WSR load cycles properly and bolt hold-open works too!

Just checked for cycling. Will check accuracy when the weather is a bit better and I can find the box of loaded ammo.

(Used a Stag lower with an RRA two stage NM trigger. Need also to check the BRO lower with the Bill Springfield single stage trigger ... but that won't be a test of cycling I think. More a test of hammer fall.)

THANK YOU, Sir!

tp555 is The Man ... his work is lovely ... measures Dead Nuts on! Frankly at this point if I found a measurement that I thought might be off, I'd doubt my measuring tools rather than his work.

(I have the tools to bend 3/16" and larger SS tubing for cars. Did not do well with the smaller, thick walled stuff. tp555 made a tube of the proper length from a rifle length tube using the bent section in the proper place. He then machined the rebate in the gas key end so the seal is appropriate. Beautifully done. This is a job I'd have done myself ... but the smaller of my two lathes won't quite hold the tube.)

Bending the tube went easy with a cheap chino tube bender.Collets or a small 3 jaw chuck holds the tube for the relief cut.Hold the very end of the tubing in a vise so it doesn't rotate and do the bend thing.If I can get the spec for the tubing and straight material I can make the gas tubes.Easy job.
