Can you tell me if I buy AR15 223 without suppresser can you just get one fitted like normal gun or do other things change Does suppression change the recoil like on a normal rifle plus reduce sound levels as well ? Do you need to change other bits if you suppress them ?

It depends on the suppressor and the gas system. Most cans will cause the rifle to be horribly over gassed. Some cans are designed to reduce back pressure, the DPT .223 mini can does this very well. The easiest way to mitigate issues caused by suppressing an AR is to install an adjustable gas block.

from what Iv seen fitting a suppressor caused shit to go in your eyes and you need to do a poor man gass buster fix with a bit of high temp silicone

was just about to sell my ar till I sorted it. now its a gem to shoot

recoil is minimal, sound suppression is great, best thing you can do to an ar15. muzzle breaks piss nabours off. get rid of them

[gimp]

the gas buster doesn't do much for a really overgassed rifle due to suppressor, you also have the issues of filthy action/mags, increased recoil (bolt/buffer moving faster = more recoil) and increased parts wear


an adjustable gas block is the best option

[Bill999]

maby for a really over gassed system, but for a moderately over gassed system id rather just the silicone, adjustable gas blocks, or the cheep ones anyway are just another thing to get bumped or go wrong to affect accuraccy
on the up side it only hurts your pocket $15

Yeah I've got a PRI gasbuster handle


I don't see how an adjustable gas block can get knocked if you have a low-pro one under your free float tube/rail. Probably beneficial for accuracy considering they'll reduce the impulse of the reciprocating mass of the buffer/BCG. Other option is a heavier buffer I guess, except you can't get a heavier rifle buffer as far as I know and no-one (except me!) has carbine length stocks on A, just A2 and various monstrosities (B&C thumbhole etc)

[Bill999]

you probably also gain 1/2 a fps extra velocity too
