问个PSA Upper的问题

CHF管子的Upper,都做好了带前瞄的gas block. 自己能换low profile的gas block吗？

能换 - 都能换 - 想换啥就换啥 - Chop it small 也行.

是的，Gas Block 我改过来了。14.5 pin and weld是不是就没法换了，即使clamp on gas block貌似也套不过去。

Pinned and Welded muzzle device 也可以去掉, 要有工具 和 决心 - !

装了 Low Pro GB 后, 如果还要 Keep it  legally as Rifle, a (new) muzzle device must be insrtalled to make up the total length of barrel at least 16" - Pinned and Welded.

有的 Vendor, 如 Voodoo, 就有那种 Pinned and Welded  "消瘦型" Muzzle Device + 管子 ...

The VDI Manimal Flash Hider has the same .750" diameter as the gas seat, allowing for a gas block to clear the flash hider.

多谢，本来买PSA的assembled upper, pinned and welded 就是为了省事，不折腾。这样看来还是买散件，然后pinned and welded together寄过来比较省事。比如rainier arms就有这个服务，40块。
