Well, let me first say I am not interested in any border wars, AND I have a BCL 102 (Canada) XCR-L (US) and Tavor 21 (Isreal)
The Tavor 21 is the proven battle rifle and with a Geissele Super Sabra Lightning Bow trigger is a rock star NR Bullpup that will shoot anything and all day long.
The XCR-L is an older model, heavy barrel with rails, (
type 2 bolt catch, type 2 mag release, type 1 rear receiver). In short is not a light rifle.
Shoots well, but does like full synthetic oil when it gets hot. Otherwise, it can act up a bit. Newer various are even better and lighter.
The newest rifle is a Gen Two BCL 102. Picked it up this spring. Had some FF and Stove Pipe issues when first new. Hirtenberger is all I shoot.
I got the local gunsmith (Murray Charlton Enterprises) to install a PA M4-72 Tactical Compensator. Murray and Tim had a good look at the BCL.
It is well built and to very tight tolerances. Little too tight, as for mine, it took somewhere between 100 and 200 rounds to break it in.
Again I use full synthetic oil and keep the BCG wet, as recommended by other owners, and it shoots well.
Today I was up at the Victoria Fish and Game Association, shot all three and let some other members shoot the 102 (bottom pic).
All three are different; all shoot well. In an urban gunfight, the Tavor is proven, and it's a great rifle. Fast to acquire targets and quick to point.
The XCR-L is also a great shooter, although this version is a little heavy to pack around. The XCR general rule is if hunting gets the light barrel, and if a range queen, pick up the heavy barrel is it will shoot a lot of rounds more accurately (when hot). Or get both and if new 223 Wylde and perhaps a used 7.62x39 barrel, BCG, gas tube, and mags. Barrel, BCG and Gas tube swaps are very quick in an XCR.
The BCL is the heaviest of the bunch but also has a big upgrade in punch. I shoot paper and steel targets with surplus 5.56 in the 21 and XCR. The 308 WIN (7.62x51) 146gr FMJ have a noticeable increase in impact when they hit steel.
The owners of the earlier BCLs reported issues, and some continue to do so today. Ryan (SFRC) reports these are being addressed. Extractors and BCGs have some issues and where replaced.
Like the 102, and any new rifles, the Badger (and Modern Sporter) and likely to have teething issues. Both BCL and ATRS, are stand up companies and will address any issues and make improvements along the production run. My wife is Kiwi. Google "Lewis Machine and Tool New Zealand rifle problems."
New rifles can have issues. Solid companies can all experience outsourcing challenges.
If you are looking for your first NR "Tactical Rifle" I would suggest you find something that is mature and proven. Or at least something that all the issues are well known and easy to address. i.e. the stock trigger in the Tavor 21 sucks.
