General silencer discussion. If you want to talk about a specific silenced rifle or pistol, it is best to do that in the rifle or pistol section for that brand.

Semi-auto 308 host

Pretty simple, I just want opinions on a good semi-auto 308 rifle to put a suppressor on.
I've wanted a 308 for years, but the guns I like are pricey, so I've never pulled the trigger on one.
I don't mean pricey like, stupid money thousandS of dollars for a name and membership fee to the cult. But most of what I've been back and forth between are, usually, at least $1500+.

So, what are some options for a 308/7.62 rifle that is reliabel, reasonably accurate at distance, and lends itself to being suppressed without much effort?
Also, I understand that 308 isn't the quietest thing around.
But let's say I have a .30 caliber can, and I would rather invest in something like 308 rather than 300blk.
I have considered bolt guns, but that's not really what I want at the moment. (I have thought a lot about a Ruger bolt action 300blk.. maybe in the future)
Guns I have heavily considered in the past include Ruger SR762, Aero M5E1, M1A Scout or Socom16, PTR91.
Of those, in the past, SR762 used to lead my favor. Really always liked the M1As too. PTR91s have always seemed cool too, and seemingly relatively cheaper, but a friend has one and that thing is pretty heavy.

I'm open to other options, that's why I'm making this post. I want to see what people like for a semi-auto 308.
I kind of feel like this should fit the bill of an 'all purpose' rifle, to some extent. Hopefully under $2000.

Stay away from the M1A its a pain since you'll need to switch some stuff out to get it to run right like a shuster gas plug and I put a delta p designs muzzle adapter on mine and after that extra few hundred dollars you'll have and exceptionally gassy gun that makes your eyes water. I can personally recommend the lwrc repr(heavy though) or the scar 17(I have two). Not cheap but you only need to buy once.

Yeah, I like M1As, but I've moved away from that as a consideration.
I've been thinking a lot about building a 308 AR. I don't really care for scars, but the lwrc reprs are very cool.
But you're talking about Crazy money for a scar or lwrc.
I don't have money like that. I was thinking a freefloated 18" barrel also. Seems like lwrc only offers 16&20". I'm sure idk why. I mean, I'm sure I'd be happy with their precision 20", and a 16" upper, but again.. craaazy money

The FAL will require modification to the gas block system. Namely, welding it and drilling a smaller port. Not a huge job, but I don't know of anyone selling aftermarket ones for those not inclined to do it themselves.

Stimpsoncat @ Fal Files has done it and is usually pretty open about specific port size he finished his with.
I don't care what your chart says

I would build your own so that you can put quality into it as the funds allow. get a matched upper and lower set, buy your parts kit (get a great trigger doe) and then move to barrels, hand guard, stock, blah. blah, blah

In semi autos, I have had good results with the DPMS G2 series of rifles. I particularly like the AP4 for driven hunts on boar. The other posters have mentioned the essentials: a decent adjustable gas block. I like the model from Superlative Arms as it bleeds the excess gas off to the front, but your mileage may vary.

Also, a stronger buffer and buffer spring can sometimes help as well. But the gas block is the most important part. Suppressed guns are simply very, very overgassed. On the AR platform many good parts exist to make adding a suppressor easier. Also, on most models the barrels already come threaded from the factory.

I cannot recommend any particular manufacturer or model as due to silly import restrictions, the suppressor markets in the US and Europe (I live in Germany) have fairly little overlap. I like the models that attach to an existing muzzle device. They have a more positive lock.

Just be mindful of the shift in POI. I own several suppressed rifles and not a single one shoots bigger groups after I attach the suppressor.
