Questions & Answers
Will it take the Magpul cheek risers? It looks like there are slots for that. Expert Answer

Those Magpul risers are not designed to be used on AR-15 rifles as they will interfere with the charging handle. They are designed to be used on bolt action rifles that use AR-15 style receiver extensions.

Great solid stock by Al, August 10, 2020
Install is easy. Stock is nice and solid. Spacers allow you to customize the length of pull. Rubber pad to keep it from slipping. Multiple sling locations, plus you can get a monopod for the back to go with a bipod up front. Excellent value!

No rattle, really tough, a couple minor incompatibilities by Dan, July 7, 2018
I bought this for an LR308 type rifle. I had previously bought the similar Magpul MOE FCS stock but being on a 6.5 Creedmoor rifle, the monopod option sold me. The MOE was kind of a rattler too. I don't like LR308 carbine style shorty buffers so I...
