Please educate me on XCR revisions, buying an XCR-L used what to look for?

[Ardent]

Afternoon, haven't looked at or played with these since they came out. Any major mechanical advantages or improvements to the late revision XCRs? Usually by two of each gun for spares and that's the plan here, want to be sure I'd have parts commonality as well and choose the best revision. I do like a folding stock, cheers and thanks folks.

I believe they are on J for the XCR-L and I don't know of any revisions for the M.

Extra parts kits from Wolverine supplies are available. Buy two of the deluxe kits. Now before anyone jumps on this I hold by this rule for any modern sporting rifle, have parts on hand.

Buy lots of buffer pads, lots and lots . Maybe it's not that bad, but it's extremely frustrating to have the rifle go down for pennies worth of plastic, so keep about three spare per rifle, especially knowing how you like to shoot in all weather.

For folding stocks if sticking with the FAST then immediately ditch the factory locking spring and go with a stronger spring. They have fixed the issue at factory, but I still found that the factory spring was lacking. The FAST stock locks up under spring tension, not mechanically.

If you're looking to buy new give it a bit and Wolverine will have the latest editions in with Keymod front ends. Otherwise if price is no object and you're looking used get the latest gen, I believe 8000 serial block or higher.

Much obliged loki, exactly the run down I was after. They still loctite addicts? I really haven't paid attention to these since they first came out, but just played with one and liked it a lot more than I would have guessed.

No. Torque everything to factory spec and it'll be fine.

That being said I loctite anything with threads on any platform. Recoil's a b!tch on threaded parts and eventually everything can shake loose.

How much life can one expect out of a buffer pad before it needs replacement?

This seems to be a hit and miss topic. Some have been reported splitting after 200 rounds, where as I personally seen one last 3000 rounds prior to showing signs of need for replacement.

My thought on that matter is what type of weather you're shooting in matters. You don't see guys reporting that they were shooting in -30, just that the buffer busted after X amount of rounds. It's a piece of plastic, and of course plastic is brittle and breaks when struck if it's frozen.

It's not that bad if I'm making it sound worse than it is. Just keep an eye on it with maintenance. It's a cheap part so having a few on hand isn't expensive.
