Folding Buttstock Options
Today we take a look at 2 folding buttstock options for the R18, both of which are either currently available from TSE or are under development by SAI for eventual TSE sale.
The first option is the Magpul Zhukov Buttstock, which mounts to the Picatinny Buttstock Rail by way of a 1" Adapter Block. Combined with the 1" Mount integral to the Zhukov Stock system, this results in a 2" non-folding projection immediately behind the rifle.
The second option is the Midwest Industries Folding Picatinny Adapter which adds 1" to the Length of Pull. This Folding Adapter is reversable, which is required to get the Buttstock to fold flat against the Right side of the R18 (rather than hung up on the Cocking Handle on the Left side).
In my view, the Midwest Industries Folding Adapter is the least obtrusive, most streamlined and better looking option of the two. It is also the least expensive option at $150 CAD for the Adapter (in stock now at TSE). Note however that you will have to reverse the direction of fold by flipping the stock over so that it folds to the Right. The Midwest Industries adapter adds exactly 1" to the existing Length of Pull, which is remedied for shorter firing postures by collapsing the Buttstock one adjustment notch.
The Magpul Zhukov Buttstock adds 2" to the overall Length of Pull, requiring that the stock be fully-collapsed to accomodate people of shorter stature. The Zhukov Stock Adapter offers an QD Sing Socket on either side of the adapter whereas the Midwewst Industries Adapter lacks that feature.
In term of incremental upgrades, the 2 x Test Rifles were returned to me with stiffer/stronger Recoil Springs (exhibiting a slightly "snappier" return to battery) as well as some revised Bolt and Carrier parts. Specifically the Bolt Cam Pin has received additional chamfering of the exposed end to aide in smooth cycling and manual operation of the action. Likewise, the end of the Firing Pin Retaining Pin has been rounded-off to ensure smooth cycling within the Upper Receiver. rIn both cases, the revised part is shown to the Left of the original version.
