Ryo decided his Remington 700 did not cut it, so he built a bolt action AR-15. Basically it is a AR-15 with a side charging handle and a blocked gas port.
Instead, I bought a 26″ Krieger AR-15 Varmatch barrel, with a 1:7.75 twist. They had these in stock, so it showed up at my apartment in about 2 weeks. To block the gas port, I simply installed the gas block off-centered (then later rotated it upside down because I was getting stung by gas and ejecta which managed to leak through the gas block and out the rear-facing hole where the gas tube would normally be).
A great looking rifle and I am sure it functions well and the bolt can probably be worked faster than many straight pull bolt actions.
