We bought the wife a new LH T-bolt when they recently became available.
Not a fan of plastic on a walnut rifle, but it is a very nice gun overall and shoots well.
Not up on Browning's manufacturing of T-Bolts, but we had watched for several months before a lefty sporter became available.
If I was wanting one, it might be a good idea to get one while they are available, as one never knows when Bro2wning will stop making them again.
