I have an All Weather Wally World 10/22. So far I've installed VCL's target hammer, edge extractor, & buffer. The target trigger takes a LOT of weight off. Yesterday I tried rapid firing but the sear wouldn't reset fast enough. My advice on that is to not replace the spring behind the trigger. After I switched it back the rifle rapid fired fine. I bought the edge extractor for my Aguila Super Colibris. 6 out of 10 rds would eject when I racked the slide so I installed the new extractor with disappointment as it didn't seem to fix the problem. I looked a little closer & noticed the extractor was rubbing against the breech so I readjusted the barrel & that seemed to help. I bought the recoil buffer due to the lower hammer spring pressure. I figured less resistance in the slide would wear my bolt out faster. The buffer is a miniature glue gun stick, that's exactly what is is so don't expect a precision made polyeurethane dowel. It hasn't disappointed me yet & takes the clap of the bolt away. If you're considering any one of these I'd highly recommend it. Volquartsen will even fix it for you for free as long as they don't have to replace any parts. Take my advice into consideration before splurging.
