I just bought a Gibbs Enfield jungle carbine in 308 at my local gunstore. Gibbs calls it the "#7", I think. It's a very nicely made rifle. The rifle started life as an Enfield Ishapore 2a1 and was converted by Gibbs to an Enfield Jungle Carbine. It's a very nice rifle with a mirror bore and a parkerized finish. New stock. All functions work like new. My experience with this rifle has been extremely positive. But it is my only experience with a Gibbs rifle. I've heard that others don't like Gibbs at all but I don't know the reason for their dislike.
I have a C&R, I'm a collector, I don't bubba-ize guns at all and I hate to see it done. But this rifle was priced right and is very functional. I realize it has no collector value but it will be a great shooter for me.
It's up to you. If you're a complete purist, a Gibb's rifle will turn your stomach. But if you realize its just a shooter and what's done is done, check it out and make sure it's put together properly and functions well. Buy it if you like it.
