I have a 16" HBAR Middy Rock River Chrome lined barrel with a YHM Diamond Rifle length rail. It is just stupid heavy. Wish I had a rail like a JP VTAC or similar, don't need all that rail. Just a scope,, flashlight, foregrip, and an old holosight! Was thinking of doing a "Heavy Feather" ie., custom profile. This is for my hillbilly SPR type use- day/night varmints etc. Thinking of going gas block dia. from chamber area to gas block, then about ".68 ish to the muzzle.....Will re stamp twist and whatnot on barrel.
I did put this upper together and it shoots great, and have a friend with a lathe. Was going to bead blast when done and cold blue.
What says the hive? This is a no money type mod, my favorite! Weight savings worth it? Will get back to you this afternoon, thanks Lockstep.
Update––- O.K. Sunday evening finds the project home parkerized. I'm waiting till tomorrow to wipe the oil off the barrel and see how I did. As far as re stamping the barrel, the original marks are still near the chamber area which was not cut down there. I guess this is a Wilson sold to Rock River, I did look online for some info about it, but didn't try to hard since I already knew what I had- Have box and papers.
For the Park I used a recipe I found online,-
One gallon distilled water, 1/3 cup Kleen strip phosphate stripper, manganese phosphate from one D cell alkaline battery (the black stuff) and some steel wool four ought.
Today I did make my own tank from an old stainless steel fire extinguisher cut in half lengthwise, and took before and after pics of the barrel, my homemade barrel wrench and related things. Will try to post these tomorrow for others to learn from...
I think the finish might be thin, and I will re bead blast and try again tomorrow.
The whole point of the exercise was to do it all myself, learn a lot, spend very little -14$ so far, and to remain self reliant as possible. Lockstep
