Quoted: I am on the verge of purchasing or building my first AR. I understand that the 14.5 barrel is legal with the permanently attached a2 flash suppressor. I really like the look of the sloghtly shorter overall rifle. Are there any pro/con to this?
Am i sacrificing any accuracy with 1.5 in less barrel? I would assume that i want a 1:7 twist anyway for better accuracy.
Any help would be appreciated, and if you have a pic of a rifle in this config that would be awesome. Thanks from a noob. |
welcome to the site!
1st, you are correct-- a perm attached muzzle device on your bbl, as long as its 16in(+) OAL is fine
std A2 FHs will not make the length cut--get an extended A2, which are a little longer--like this:
A2 extendedof course, for that price, i'd get the Phantom
shorter bbl=less vel. which usually, if not always, leads to less frag range (pertaining to the 5.56 bullet), which is pretty essential for most 5.56/.223 loads
accuracy, for all practical, intents and purposes is not affected by bbl length--only velocity is affected
there are other cons to a perm attached muzzle device, including: since its perm attached, you cant just switch out the muzzle device (say you wanted a vortex instead of teh A2 down the road) as easily, of if you wanted a std FF tube, or replace your FSB--most require that you remove your perm attached muzzle device
twist, not necessarily; it all depends on the loads you will use and ammo type...in general, for 5.56/.223, 1-9, 1-7, and 1-8 are the most used in the civi area
read this:
www.ammo-oracle.comthere are some colt pins which are not compatable w/ the std ARs, but for the most part, they are all the same size w/ the pins in the lower/upper (your RRA and CMMG will work fine)
since everyone is posting pics of 14.5+perm FHs, my CAR-15 like AR:
