I got this stock with an A5A2 shorty grip but not the Air-through version. You can go and check out that review if you like. FIrst and formost, the preious stocks i have used are not very good and do not even touch this stock in terms of performance. i got this stock because even though i had a Lapco offset sight rail, i still could not see into my Armson gunsight with my mask, a Proto EL Switch.
CONSTRUCTION: This stock is very durable. the injection molded plastic is very stong and you can just feel the quality when you hold it. i can tell that this will last me for a while. The stock is a bit long. i like it because with my 20" barrel is makes my gun look really intimidating. However i can see it might affect some people and that for that reason, i suggest that they dont get it if the like to get up close and personal in their game. But of course, it is all personal preference. Basically the stock is the same length as a fully extended Collapseable stock (11" i believe). If i am wrong, leave a comment, not a dispute and i will fix it immediately.
ERGONOMICS: The rubber but pad on this marker makes your A5 very stable and prevents it from slipping while it is against your shoulder. It is a very stable shooting platform. The cutout does work and that made me really impressed. I am now able to see into my Armson gunsight because of this stock. A very good feature becasue now i didn't waste my money on a great sight.
INSTALLATION: I did actaully have a hard time installing this stock. not hard to degree of impossibility, just hard enough that i needed a hammer to knock the pushpins in. I also found that i need a hammer to take them out. This would hinder the ability to field strip. i however would never attempt a stip of a marker on the field other than barrel cleaning. Still, i now have to carry a small hammer in my kit with me.
Overall this is a great stock and i recommend it to anyone except those who would find the permanent length cumbersome. I especially like the cutout in the stock that allows you better visual access to your sights. i did find that i still needed an offset rail to use my gunsight, but at least i could see the red dot now because of my stock. The rubber buttpad is also a great addon that enhances the performance of the stock.
