Got a new project in the works, and I'd like to put a 20" Faxon barrel on it. I used a BA factory pinned low profile has block on my first build, and that process went extremely smooth. I see that Aim Surplus will pin on a low profile block on Faxon barrels, anyone ever try that? I would like to avoid shipping out a barrel to get pinned if possible, though that's certainly a deal breaker. Hoping? to hear some experiences and impressions if anyone had tried the Aim route. Thanks!

I got one of the 16" Gunnar barrels from AIM w/ pinned GB.
They are gtg.
It comes with a roll pin and is pretty easy to install once the barrel is ready to go.
Love my Faxon barrels btw. Have so many now, I think I have lost count at this point.

I too have a 16" Faxon from Aim, the gas block is set screw and roll pin, you must install gas block yourself.  I'm very pleased with mine.  I believe Aim is the only vendor that will ship a Faxon already drilled for the roll pin.

Thanks for the input. Nathan, speaking as just one guys opinion, a drilled gas block from the factory would win a sale for me. I chose the BA barrel over your Gunner for my first build for that reason alone. I'm not a builder, just a newb assembler, and having a properly positioned and drilled gas block is a HUGE benefit. I would chose a factory drilled GB over a secondary vender every time as well. I like everything I read about Faxon barrels, and need to decide on a 20" reasonable? weight barrel, and just found out BA is going to offer a 20" fluted as well. For me alone, they'd win if they drill it as nice as the 16" I bought. It just needs to be drilled, not fully installed, and that's how BA ships them. I'm not opposed to ordering through Aim, but it's not my preference. Either way thanks for the response.

aim surplus is a fantastic vendor. my mail man "stole / lost" a daniel defense barrel i ordered from aim, even though usps showed that the part was delivered to me (it was not) aim surplus not only refunded my money (sold out of discontinued product that was on a blow out sale that was posted in arfcom gd and inventory lasted about 10 minutes ) but they had my refund back to me (bank) in like 2 days. by far the best customer service i have ever experienced. i would have no issue recommending them and am fairly confidant they would take care of an issue should it arise.

i have no idea about faxon, they seem to have good reviews, they seem to respond well to queries here. i may have to give them a shot one day, i like the specs of their super light weight .308 barrel it just isn't in the budget right now.

Good experiences all around from both Faxon and AIM.

Good to hear positive experiences, thanks.

99% pleased with the 10.5" 5.56mm barrel I bought for my pistol build.

The roll pin it came with was kind of cheesy, so I bought a 3/32" stainless dowel pin of 3/4" length and used that instead of the very short roll pin that was supplied with the barrel/gas block.

The only thing I wish Faxon would change / offer, is a smaller gas port as an option for people that only shoot good 5.56 pressure ammo and none of that Russian garbage.
